how can i Specify what ions are present in solution upon dissolving each of the following substances in water: ZnCl2, HNO3, (NH4)2SO4,Ca(OH)2
Answered by DrBob222
I think the idea in this question is to make sure you associate those atoms together that make polyatomic ions.
ZnCl2 = Zn^+2 + 2Cl^-
HNO3 ==> H^+ + NO3^-
(NH4)2SO4 ==> 2NH4^+ + SO4^=
