    I am continually having trouble with this type of problem. Can some one explain what makes "B" the most soluble in water. I understand that all possible choices except BaSO4 are soluble, so why B. Thanks much

    I think it is because according to the rules of solubility NH4 anything is soluble. The fact that B is "most-soluble", may be due to the fact that there are 3 NH4's on that molecule.

    yes BaSO4 is insoluble but you should immediately also be able to eliminate AgCl because all silver lead and mercury alts are insoluble. SO now that you eliminated those 2 chose the most soluble one left and like DRHOYA said NH4 is soluble so that makes B correct
