    1.Write equations for the neutralization reactions that result in the formation of the following salts:

    a) lithium carbonate
    b) copper (II) chlorate
    c) aluminum sulphate
    d) ammonium iodide

    2.For each of the following situations, identify those for which a reaction is likely to occur. For those that do occur, write a net ionic equation.

    a) Chromium dipped into silver nitrate.
    b) Gold immersed in hydrochloric acid.
    c) Nickel pellets dropped into calcium acetate, Ca(C2H3O2)2.
    d) Aluminum dropped into a bath of sulphuric acid.
    e) Zinc dipped into a solution of lead (II) nitrate.

    3.An industrial plant that specializes in cleaning up waste liquids is confronted with a problem of separating the metal ions found in a large vat of solution. By analysis, the solution was found to contain varying quantities of silver, barium, and iron (III) ions. Suggest a procedure for separating the metal ions be precipitation.

    4. A chemist wishes to prepare 200mL of a saturated solution of BaF2, the concentration of which is 6.3 x 10-3 mol/L. Determine the mass of BaF2 that will be needed to make up the 200mL of the solution.
