H3O+, Br1−, and water molecules

the nitrate (NO3−) salt of the metal ion All nitrates are soluble.

Ni(OH)2, Mg(OH)2 This is what I think: Solubility rules say all hydroxides are insoluble except for compounds of Group 1 elements, so LiOH and KOH are not the answer. Calcium is moderately soluble, leaving the other two.

CrPO4 and Pb(OH)2 All nitrates are soluble, so LiNO3 would dissolve. Sodium & potassium salts are soluble, so NaBr and KOH are out. Chlorides in this case are soluble, so RbCl is out, leaving the other two.
