The graph below shows the solubility of a salt as a functionof pH. Which of the following choices explain the shapeof this graph? (a) None; this behavior is not possible.(b) A soluble salt reacts with acid to form a precipitate,and additional acid reacts with this product to dissolve it.(c) A soluble salt forms an insoluble hydroxide, then additionalbase reacts with this product to dissolve it. (d) Thesolubility of the salt increases with pH, then decreases becauseof the heat generated from the neutralization reactions.
