Question

Write a balanced equation for the dissociation of Mg(NO3)2. I wrote Mg(NO3)^2(s)==>Mg^2+(aq)+NO3^3-(aq)
That isn't the answer in the book. Can someone explain to me how dissociation works?

Answer 1

I would have written just as you did but 2NO3^-(aq). The equation you wrote isn't balanced. If the answer in the book is different, perhaps we can point out the problem if you post the answer. Also, the book may have wanted H2O in there as in Mg(NO3)2(s) + H2O ==> Mg(2^+(aq) + 2NO3^-(aq)
