For each of the following water-soluble compounds, indicate the ions present in an aqueous solution:
NaI
K2SO4
NaCN
Ba(OH)2
(NH4)2SO4

would the answer to NaI be Na+ I-? Should there be more to my answer? Would K2SO4 be K+ SO-? Thanks for the explanation.

  1. NaI is ok.
    K2SO4 will be K^+ and SO4^-2
    NaCn is Na^+ + CN^-
    Ba(OH)2 is Ba^+ and OH^-
    (NH4)2SO4 is NH4^+ and SO4^-2
    I think the purpose of this question is to help you concentrate on knowing the polyatomic ions such s sulfate, cyanide ion, hydroxide etc.
