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.© BrainMass Inc. brainmass.com July 18, 2018, 3:18 am ad1c9bdddf
