Question

I tried using the answer you provided but the online system I am using is not taking this as a correct answer. This is the answer you provided: AgCl(s) + H2O(l) ==> Ag^+(aq) + Cl^-(aq). PLEASE HELP!! Thanks


My original question: Write the equation for the dissolution of AgCL(s) in H20(I).Express your answer as a chemical equation. Identify all of the phases in your answer. I tried writing it as AgCl <> Ag+ + Cl- but this is incorrect.

Answer 1

I don't know. One piece of trouble with the equation I provided is that it isn't balanced [H2O(l) on the left but no H2O(l) on the right.] USUALLY we write dissolution equations and don't show the water (with water being understood) as AgCl(s) ==> Ag^+(aq) + (Cl^-(aq) but that doesn't answer the original question because the original question has H2O(l) in it as a reactant. The only other suggestion I have is to show H2O(l) on right as well. AgCl(s) + H2O(l) ==> Ag^+(aq) + Cl^-(aq) + H2O(l). When I do that, however, I want to cancel the H2O(l) because it appears on both sides and that justifies not showing water in the first place. Again, however, the original equation has H2O(l) as one of the reactants and that lead me to think it must be included. When you find out I would be interested in knowing the answer. Perhaps I'm missing some fine point.

Answer 2

H2O acts as a ligand and binds to Ag. This gives and equation of AgCl +2H20 - Ag(H2O)2 + Cl
