Hello!!!!!! :D

hey, i need some help with chem  :o

i found this question from one of the past papers:

why are we not supposed to add sulphuric acid directly to dry ammonium salts??

thanks!

 ;D

Vin:

sulfuric acid is a strong acid .. adding to 'ammonium salts' would be a vigorous reaction.. diluting the acid might help
