look im not going to do your homework for you.

Split the compound on the left up. Look at the positive and negative ions. Link the correct ion, the one with opposite charge, to the extra ion you are given in the problem.


This is to illustrate SOLUBILITY RULES, one of the most important things you HAVE TO MEMORIZE in chemistry.
