Check on the internet for the ratios used by comercial factories, then prepare a solution from glycol and water in the given proportion. That's all!!!

Yes.  Solutions are made when two a substance (solute) is dissolved in another substance (solvent).  In this case, it is a homogeneous mixture since it is consistent throughout, otherwise, it would be called a heterogeneous mixture.

The beans are soaked in water which disolves the caffeine. It also disolves other compounds which give coffee its flavor. To restore the flavor, the water is filtered through activated charcoal to remove the caffeine, then the water is put back with the beans and the beans are dried.

0.5%solution means 500mg.( 1/2gms )of solute in one liter of solvent.

In chemistry, concentration or Mass Percent is the measure of how much of a given substance there is mixed with another substance. This can apply to any sort of chemical mixture, but most frequently is used in relation to solutions, where it refers to the amount of solute dissolved in a solvent.\n\nTo concentrate a solution, one must add more solute, or reduce the amount of solvent (for instance, by selective evaporation). By contrast, to dilute a solution, one must add more solvent, or reduce the amount of solute.\n\nThere exists a concentration at which no further solute will dissolve in a solution. At this point, the solution is said to be saturated. If additional solute is added to a saturated solution, it will not dissolve. Instead, phase separation will occur, leading to either coexisting phases or a suspension. The point of saturation depends on many variables such as ambient temperature and the precise chemical nature of the solvent and solute.\n\nQualitative description\nOften in informal or non-technical language, concentration is descibed in a qualitative way, through the use of adjectives such as "dilute" or "weak" for solutions of relatively low concentration and of others like "concentrated" or "strong" for solutions of relatively high concentration. Those terms relate the amount of a substance in a mixture to the observable intensity of effects or properties caused by that substance. For example, a pratical rule is that that the more concentrated a chromatic solution is, the more intensely coloured it is.\n\nQuantitative notation\nFor scientifical or technical applications, a qualitative account of concentration is almost never sufficient, therefore Quantitative notations are needed to describe concentration. There are a number of different ways to quantitatively express concentration; the most common are listed below.\n\nNote: Many units of concentration require measurement of a substance's volume, which is variable depending on ambient temperature and pressure. Unless otherwise stated, all the following measurements are assumed to be at standard state temperature and pressure (that is, 25 degrees Celsius at 1 atmosphere or 101.325 kPa).\n\nMass percentage\nMass percentage denotes the mass of a substance in a mixture as a percentage of the mass of the entire mixture. For instance: if a bottle contains 40 grams of ethanol and 60 grams of water, then it contains 40% ethanol by mass. Commercial concentrated aqueous reagents such as acids and bases are often labeled in concentrations of weight percentage with the specific gravity also listed. In older texts and references this is sometimes referred to as weight-weight percentage (abbreviated as w/w).\n\nMass-volume percentage\nMass-volume percentage, (sometimes referred to as weight-volume percentage and often abbreviated as % m/v or % w/v) denotes the mass of a substance in a mixture as a percentage of the volume of the entire mixture. Mass-volume percentage is often used for solutions made from solid reagents. It is the mass of the solute in grams divided by the volume of solution in millilitres and multiplied by one hundred .\n\nVolume-volume percentage\nVolume-volume percentage or % (v/v) describes the volume of the solute in mL per 100 mL of the resulting solution. This is most useful when a liquid - liquid solution is being prepared. For example, beer is about 5% ethanol by volume. This means every 100 mL beer contains 5 mL ethanol (ethyl alcohol).\n\nMolarity\nMolarity (M) denotes the number of moles of a given substance per litre of solution. For instance: 4.0 litres of liquid, containing 2.0 moles of dissolved particles, constitutes a solution of 0.5 M. Such a solution may be described as "0.5 molar." (Working with moles can be highly advantageous, as they enable measurement of the absolute number of particles in a solution, irrespective of their weight and volume. This is often more useful when perform

The solute would the the silver nitrate because it is desolved in the water.  Water would be the solvent.

The answer depends on what that substance it is and what the solvent is. Generally in nature, like dissolves in like. If you have a polar substance, it generally dissolves in any polar solvent. For example, salt (NaCl) is an ionic compund, it dissolves well in a polar solvent, such as water. However, you may find it difficult to dissolve NaCl in an organic solvent, such as hexane. On the other hand, many marker use some sort of organic ink, therefore, they can not be dissolved by water. However, you can try to dissolve them using alcohol.\nHaving said that, it is not absolute that all polar substances can not be dissolved in organic solvent or vice versa. If you have a compound, such as ethanol (which is organic substance), it can dissolve in water (which is a polar solvent). This is because ethanol molecule has a structure (the OH group) that can interact with the water molecule to form hydrogen bonding. However, if you use a much heavier organic compound, you will find it very difficult or even impossible to dissolve it in polar solvent.

Vodka has a proof number which is 2 times the % of alcohol. Solvent is the liquid in greater amount. Solute is the one in lesser amount. So if the vodka is 80 proof, it is 40% alcohol, and the alcohol is the solute, and water the solvent.

"Coffee has more caffeine than tea" --> This is the general misconception among people.\n\nTEA actually holds a higher caffeine content than coffee. Note that the TEA i'm referring here is English tea.\n\nChinese tea and Green tea, however, holds a very small amount of caffeine. These 2 types are consider the most healthy form of tea (with caffeine amount in green tea the lowest)

Basically, in hot tea, the water molecules are moving at a much faster rate than cold water molecules.  Thus the number of collisions with sugar molecules is higher, therefore there is faster dissolving time.  Don't believe me?  Try ice water, room temperature water, and hot water, and without stirring see which one dissolves a teaspoon of sugar first.

The solute (lesser component)is the substance which is dissolved in a solvent (greater component).\n\nHope this helps,\nUltimeaciax

1) Decide what solvent you want to use: water or organic?\n2) Decide how much solution you want: 1L?\n3) Check the solubility of phenol in the solvent you choose. And calculate how much phenol you'll need by weight to make a saturated solution\n4) Find out the relationship between solubility and temperature.\n5) I assume you want to make a saturated phenol solution at room temperature. If the solubility increases as temperature goes higher, add a bit more phenol than needed (from the calculation above) to the solvent. \n6) Heat the flask or beaker that contains the solvent and phenol until all phenol dissolves.\n7) Let the container cool down to room temperature.\n8) If no phenol crystalizes the solution is over-saturated. You may rub the side of the flask or beaker to help phenol crystalize.\n9) You have your saturated phenol solution!!

A solute is the solid that is dissolved in a liquid. The solvent is the liquid in which something is dissolved in. For example, with salt water, the Na and Cl are the two solutes, and the H2O is the solvent.

Yup, non-polar solvents.  If acetone, alkanes, or toluene don't work, then go with petroleum ether(hist. ligroin) that dissolves alot of things.

aqueous?\n\nany solute dissolved in water is then referred to as an aqueous solution. all acids are referred to as aqueous.\n\nex: HCl(aq) and NaCl(aq)
