Title: Acid
Post by: rajiv on July 20, 2013, 01:56:10 AM

Hi all,

If i have an unknown acid (may be HCL or H2SO4) then how should i detect the acid with the simple home chemicals ?

Can u suggest which simple home chemical reacts with one acid and not other to detect the same.

pH paper.  Hold wet ph paper above conc. HCl and it will show acidic.  Sulfuric is not volatile and will show no response from this test.

Calcium chloride
http://en.wikipedia.org/wiki/Calcium_sulfate
Calcium sulfate

I found a source that says Calcium chloride will form a precipitate with sulfuric acid and not hydrochloric acid

Just used GOOGLE and WIKI

by the way they suggested silver nitrate for nitric acid = it will form a precipitate
