What is a Tris solution?
115716
Tris is generally used as a buffer to keep a chemical reaction at a stable pH. It has a pKa a 6.95 and 8.3. This means it is a polyprotic acid and base because it has two pKa, meaning it has two differnt places it can accept protons or donate protons ( you might want to review bronsted-lowry definitions). A buffer is a solution of a weak acid and weak base, since Tris is both, you only need it to create it as a buffer.\n\nTris stands for trishydroxymethyl methylamine, now you know what people never use the whole name.

By saponification (the way soap is made), ie treating the oil with a strong base, eg NaOH, then neutalizing the salt formed with acid, eg HCl.\n...RCOOR'... + NaOH ---> RCOONa + HOR'\n...RCOONa + HCl ---> ...RCOOH + NaCl\nThis is usually performed in aq phase, as an emulsion to start.  In the case of triglycerides, the salts and liberated glycerine are all soluble in water...but upon neutralization the acids precipitate out, and can be washed free of NaCl and glycerine.

Ultrasonic cleaners might be the best solution.\n\nHere is an excerpt from the source listed below: \n\nAlthough a range of possible alternative products is available today, experience has shown that substitution of TRI is not easy and even not feasible for a number of specific cases, either for technical or economical reasons. For all cases, substitution of TRI needs a thorough evaluation of all process aspects. For this reason we intend to work with the authorities in order to prevent a blanket implementation of forced substitution, and allow sustainable and continued safe use of TRI. \n\nThe alternatives you will probably consider first are the chlorinated solvents perchloroethylene (PER) and methylene chloride (MC). They match closest the technical features of TRI, such as non-flammability, high solvency power, a wide range of material compatibility and excellent drying and recycling properties.\n\nBeside PER and MC, you have probably also heard about other alternatives such as aqueous (water-based) alkaline systems, flammable solvents (e.g. hydrocarbons or modified alcohol based formulations), supercritical CO2 or hydrofluorocarbons (HFCs), etc.\n\nIt is impossible to say definitively which technology is best. That depends on your specific application, on what you are cleaning, which materials you want to remove, the cleanliness required, the variability of the parts cleaned, the throughput to be achieved, the cycle times, etc. \n\nFor example, for the cleaning of parts between two water-based manufacturing steps (e.g. galvanising), aqueous systems may be better, since parts are put into water phase again later and no energy-intensive drying step to remove the water is required. \n\nIf you need to have very clean and dry surfaces (for coating or surface hardening, for example) and if you have a variety of different metals or blind holes, narrow distances and very fine orifices or a lot of residual oil to clean, hydrocarbons or aqueous systems may not clean and dry well enough. In these cases, chlorinated solvents will offer most often the best solution as they are compatible with most materials, have a high cleaning power, are easy to dry, don't leave residual films and are easy to recycle with high quality by distillation. In addition, chlorinated solvents are today best suited to be used in modern closed systems with minimal losses. Their ecological performance has very much increased and, when used in well-operated metal cleaning systems, they outperform aqueous cleaning as long as drying is required. This has been shown by a Life Cycle Analysis carried out by Ecobilan. \n\nPER comes closest to TRI in technical performance and is often the first choice candidate as an alternative to TRI. However, it shows clear inherent technical differences, which need to be taken into consideration. On one side, PER offers a lower volatility and therefore is advantageous to minimise emissions in closed equipment. On the other side, PER has a lower solvency power and is therefore normally used at a higher cleaning temperature to achieve similar performance. This may raise concerns regarding the compatibility with specific metal working fluids and temperature-sensitive parts. \n\nMethylene chloride (MC) shows excellent cleaning properties already at low temperatures, favouring the cleaning of temperature sensitive parts. However, its high volatility makes emission control more difficult and requires special equipment.\n\nHydrofluorocarbons (HFC) and hydrofluorocarbon ethers (HFCE) are very expensive and show very limited solvency power. A thorough evaluation of the global warming potential is also required to choose the adequate product.

Tri state is a feature of some digital electronic devices which allows a connector (pin) to either act as a normal output, driving a signal onto a line, or to be "tri stated" - set to a high-impedance ("high Z") condition.  This allows other outputs to drive signals onto the line.  Often the same connector also functions as an input when its output circuitry is tri stated. Tri-state outputs are typically used for the connection of several digital circuits to a shared (bus) onto which any one of them may output data for the others to input.

It'd be basic speaking qualitatively. NH3 is a base so any amount in water would make the solution basic.

Trinity is not excepted because people do not understand the meaning but they think they do but are wrong. The true meaning you said before. Three + unity = trinity. 1+1+1=3. The 3 being as a single digit representing God but containing 3 whole separate numbers representing Father, Son, and Holy Spirit. These 3 are equal but have diferent functions. an egg contains 3 parts but is one also. 3 in 1 motor oil has 3 diferent typs of lubricating substances but are mixed as one, yet have diferent lube propertys and purposes. Trinity has a complex understanding in which many people will not agree because of thier lack of understanding. 2 people will believe the same thing but one will deny the trinity.

Tri-sodium phosphate.  TSP is available at Ace Hardware stores (no plug intended, that's just where I found it.)  This is a powder that you mix with water.  It can blister your skin though if you get it on you and don't rinse it off quickly - use latex/rubber gloves.  Mix some up, use it on a small un-noticeable patch of the material you want to clean, and see how it works.  You should just be able to spritz or sponge it on and rinse away the cleaner with the dirt thirty seconds later.

"Trinity" is a term that is not found in the Bible but a word used to describe what is apparent about God in the Scriptures. The Bible clearly speaks of God the Father, God the Son (Jesus Christ), and God the Holy Spirit...and also clearly presents that there is only one God. Thus the term: "Tri" meaning three, and "Unity" meaning one, Tri+Unity = Trinity. It is a way of acknowledging what the Bible reveals to us about God, that God is yet three "Persons" who have the same essence of deity.\nSome have tried to give human illustrations for the Trinity, such as H2O being water, ice and steam (all different forms, but all are H2O). Another illustration is an egg having a shell, egg yolk and egg white, but this egg illustration shows that there would be "parts" to God, which isn't the case.\n\nGod the Son (Jesus) is fully, completely God. God the Father is fully, completely God. And God the Holy Spirit is fully, completely God. Yet there is only one God. In our world, with our limited human experience, it's tough to understand the Trinity. But from the beginning we see God this way in Scripture. Notice the plural pronouns "us" and "our" in Genesis 1:26 -- Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground."\n\nThough not a complete list, here is some other Scripture that shows God is one, in Trinity: \n\n"Hear, O Israel! The LORD is our God, the LORD is one!" (Deut. 6:4)\n\n"I am the LORD, and there is no other; Besides Me there is no God." (Isa. 45:5)\n\nThere is no God but one. (1Cor. 8:4)\n\nAnd after being baptized, Jesus went up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove, and coming upon Him, and behold, a voice out of the heavens, saying, "This is My beloved Son, in whom I am well-pleased." (Matt. 3:16-17)\n\n"Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit." (Matt. 28:19)\n\nJesus said: "I and the Father are one." (John 10:30)\n\n"He who has seen Me has seen the Father." (John 14:9)\n\n"He who beholds Me beholds the One who sent Me." (John 12:45)\n\nIf anyone does not have the Spirit of Christ, he does not belong to Him. (Rom. 8:9)\n\n"Joseph, son of David, do not be afraid to take Mary as your wife; for that which has been conceived in her is of the Holy Spirit." (Matt. 1:20)\n\nAnd the angel answered and said to her [Mary], "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; and for that reason the holy offspring shall be called the Son of God." (Luke 1:35)\n\n[Jesus speaking to His disciples] "And I will ask the Father, and He will give you another Helper, that He may be with you forever; the Spirit of truth, whom the world cannot receive, because it does not behold Him or know Him, but you know Him because He abides with you, and will be in you." ... "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him, and make Our abode with him." (John 14:16-17, 23)
