Whitch acts more advertly to plastic, metal, flesh: hydrocloric or sulfuric acid?

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.

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

Ascorbic acid is Vit C.  Acidic acid is Vinegar.

Hi dude,\nHere's the rescue:\n  Acid is a chemical substance which reacts with a base to form salt and water, or;\n Acid are the substances fomed when metals react with water .\n\nCitric acid gives lemon juice taste.\n\nAcid have "Sour " taste\n\nSubstances which have sour taste contain acids, like, lemon, apple, milk.

Plastic state.  \n:-) Hope this helps!

Ferric sulfite, or iron (III) sulfite

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

Citric acid is what really gives it kick!  (as opposed to phosphoric acid used in Coke and Pepsi)\n\nhttp://oxygen.chem.uidaho.edu/ifcchem111/LabMaterials/titration.pdf

water, rubbing alcohol or if nothing else acid :P(dont really do acid)

formic\n\nFormic acid (systematically called methanoic acid) is the simplest carboxylic acid. Its formula is CH2O2 or HCOOH.

No. The body metabolizes light metals quite well. The aluminum present in the brain is coincidental; it is not a cause.

In the case of metals what happens is that the protons "steal" the electrons of the metal to evolve a H2, or hydrogen gas, in doing so, the metal for example Fe, turns to Fe++ which will dissolve, if the acid used is HCL then you'll get as products H2  and Iron Chloride, if the acid is sulfuric, you'll get H2 and Iron Sulfate. This is completely electrochemical, whereas when an acid attacks  cement is just chemical, and what evolves is carbon dioxide, with skin, I'm not so sure.

Mostly citric acid (like all citrus fruits), some ascorbic acid (vitamin C - also like all citrus fruits)

Yes, but then it wouldn't be a Kjeldahl reaction by definition.  I have used a Kjeldahl flask for many forms of digestion, and typically used perchloric acid in place of sulfuric.

Certin metals which are much more electropositive than hydrogen(viz. metal which are placed above hydrogen in the electro-chemical series) react with many acids and liberate hydrogen gas.in those cases ,the displcement of hydrogen of the acids takes plce diretly.but in majority of cases,this displacement process offurs through reaction between the acids and the oxides or hydroxides of metals.\nAcids also charatrised by their tendency to react with metal carbonates and bicarbonates evolving carbon dioxide.
