Ammonium acetate + H2SO4
« on: September 05, 2008, 07:26:49 AM »
Hi all,
I would like to know what would happen if I add 98% sulfuric acid to 30% Ammonium acetate solution. Will the acetate be converted to ammonium sulfate? The amount of sulfuric acid added was a little more than the stoichiometrically required amount (more than the half the number of moles of ammonium acetate, since every two moles of amm. aetate should require one mole of sulfuric acid.)
I did this at room temperature.
Please comment.
Thanks.

My bet is that you will end with ammonium sulfate and plenty of acetic acid stink around, as it is volatile. Note, that second proton of sulfuric acid is not as easily given away as the first, so your idea about stoichiometry may not survive glass test.

I can be wrong, though.

Right, I thought the same.. That's why added more than stoichiometric amount of sulfuric acid. Thanks anyway!!
