Reaction will appear as a double displacement reaction where counterions are being switched
For ionic compounds, charge of ion goes to the subscript of the counterion.
K2S (aq) will dissociate as K+ and S2- while Ni(NO3)2 as Ni2+ and NO3-
What precipitate (if any) will form from the following reaction?
K2S (aq) + Ni(NO3)2 (aq)
