    This problem gives a detailed solution on how to use the Ksp to calculate the maximum solubility to a neutralization solution. This sample uses as an example the reagents NH3 and MgCl2.

    To 0.350 L of 0.150 M NH3 is added 0.150 L of 0.100 M MgCl2 . How many grams of (NH4)2SO4 should be present to prevent precipitation of Mg(OH)2(s)?
