    (b) A solution of copper (II) sulfate, CuSO4, was poured into a galvanized (zinc-coated) bucket.
    (c) Copper metal was dipped in a solution of sodium chloride, NaCl.
    (d) Silver nitrate, AgNO3, and potassium chloride, KCl, are mixed.
    (e) Potassium chloride, KCl, is mixed with iodine, I2.
    (f) Aluminum sulfate, Al2(SO4)3, and barium nitrate, Ba(NO3)2, solutions are mixed.
    (g) Sulfuric acid, H2SO4, and potassium hydroxide, KOH, solutions are mixed.
    (h) A potassium bromide, KBr, solution is mixed with chlorine, Cl2, gas.
