PREDICTING THE PRODUCT OF A PRECIPITATION REACTION

Will a precipitation reaction occur when aqueous solutions of $CdCl_{2} and (NH_{4})_{2}S$ are mixed? If so, write the net ionic equation.

STRATEGY
Write the possible reaction, identify the two potential products, and predict the solubility of each. In the present instance, $CdCl_{2} and (NH_{4})_{2}S$ might give CdS and $NH_{4}Cl$ :

?? $CdCl_{2}(aq) + (NH_{4})_{2}S(aq) → CdS + 2 NH_{4}Cl$ ??
