muriatic acid or hcl?

The best use of HCl is for washing / cleaning the toilet bowels and ceramic tiles. It can effectively remove white scales usually deposited on the faucets , showers etc. (Use 5 times diluted for this purpose). DO NOT USE ON NATURAL MARBLE. It will instantly dissolve the upper surface of the marble tiles.\nIt only is a hard stain / debri removal agent NOT a disinfectant.\nBE VERY CAREFUL while using the acid as it can cause severe burns on skin and irreversible damage to eyes if in contact.

Concentrated Nitric Acid and copper.  Be careful.  Nasty stuff... really!

Acetic acid is ethanoic acid, not methanoic.  It is methane carboxylic acid, CH3COOH.  You account both carbons in the name.\n\nhttp://www.jtbaker.com/msds/englishhtml/a0326.htm

it usually creates an acid  like HCl, HF, H2SO4

pH minus is a dry form of acid (Sodium Bisulfite.) Use either it or muriatic acid to LOWER pH. It also LOWERS Total Alkalinity when used in small amounts frequently.

They both dissociate completely in water, but sulfuric is technically the stronger acid.  I think that that's what they use for metal etching as a matter of fact, but I could be wrong.  Anyway, metal would be more adversely affected by sulfuric, as would flesh (although they both hurt pretty freaking bad).  I'm sure it's the same with plastic.  A better way to dissolve plastic, though, is organic solvents such as THF.

Stomach Acid contains HCl.\n\nHCl is also commonly known as Muriatic Acid and many toilet bowl or metal cleaners contain it as well.  \n\nMuriatic Acid is made in pills to balance the pH and sanitize water in swimming pools.\n\nThe local anesthetic used by dentists to decrease pain and discomfort also contains little HCl.

If you are working in a chemical lab, you should have gotten this answer during your safety training.  However, in the case of most strong acids (HCl, HBr, HI, H2SO4, etc.) you should flush with lots of water.  If irritation persists, you should seek medical attention promptly bring with you the MSDS for the chemical you spill on yourself.  If you spilled HF, you are in deep trouble.  However, I doubt you could have gotten access to HF without knowing the appropriate precautions to take.\n\nMedically, some acids are used in the removal of warts (among them is trichloroacetic acid).  The alternative there is freezing them off with liquid nitrogen.

I used to use some stuff called "CLR" that used to work fairly well.  I've been told coke will work, vinegar, basically anything acidic will "eat" the gunk off.

It's not really a valid question. The only diprotic strong acid is sulfuric acid (H2SO4) with the loss of its second proton being weak. Otherwise, diprotic acids are weak.\n\nIf you're asking for a comparison between something like HCl or HNO3 and H2SO4, you'd have to consult chemical literature.

Did you really need to post this question twice in one minute?\n\nBoth hydrochloric (HCl) and sulfuric (H2SO4) acids can damage human flesh -- the severity of damage and the speed at which it happens depends on the concentration of the acid.\n\nThe same applies to many metals -- the stronger the acid, the more rapidly the acid corrodes and dissolves it.\n\nPlastics are another thing altogether.  Some plastics are completely impervious to both acids, no matter what the concentration.  Other polymers are slowly attacked by the acids, slowly rendering them brittle.  I can't think of any specific polymers off the top of my head that are incompatible with HCl and H2SO4, but I'm sure there are some.

I entered that into the Sigma site and it suggested that maybe I meant muramic acid.  And you can find an FT-IR spectrum on their site.  I really just suggest going to various chemical supply websites and looking at their information.  There are as many spectra as their are ways of testing for the presence of that acid.

Methylamine (CH3NH2) and methylammonium chloride (CH3NH3Cl) would be a good buffer in both are in solution together in appreciable concentrations.\n\nNitrates, chlorides, and sulfates (either as acids or salts) will not act as buffers as those anions have no tendency to act as bases (they are the anions from strong acids, which are "strong" because they dissociate completely in solution).  The same with alkali metal hydroxides, which are strong bases.

Hydrochloric acid will react with metals ABOVE Hyrogen in the activity series of metals to produce Hydrogen gas.\nThe metals will displace Hydrogen from the acid and make a metal salt (which is usually in solution).\n\nSo if we say that [A] is a generic metal above Hydrogen in the activity series that has a normal oxidation state of +1, then the reaction would be as follows,\n[A] (s) + HCl (aq) --> H2 (g) + [A]Cl (aq)

sulfuric acid is the way to go.  \n\nwarms up the inside as you drink it.
