a.) barium chromate, BaCrO4, is insoluble in basic solution butdissolves readily in acidic solution.
b.) The addition of NaOH to the iron (III)- thiocyanateequilibrium causes the red color to disappear and a rust coloredprecipitate to form.
c.) The solubility of lead chloride, PbCl2, in 0.10 M HCl ismuch lower than in pure water.
d.) Limestone, CaCO3, is an insoluble salt but will dissolve inacid.
e.) For part C, how does the rate of the reaction vary as thetemperature is increased? Explain.
