Question

PRE-LABORATORY EXERCISES: 1. On the basis of the solubility rules for salts, predict the products and write BALANCED equations for each of the following reactions. If no reaction occurs, write "no reaction". (a) Pb2+ (aq) + SO42- (aq) ? (b) Cu(NO3)2 (aq) + Na2S (aq) ? (c) Fe(NO3)3 (aq) + NaOH (aq) ? (d) Al (OH)3 (s) + HNO3 (aq) ? (e) FeCl3 (aq) + NH3 (aq) + H2O (l) ? (f) Pb(NO3)2 (aq) + HCl (aq) ? (6 marks) 2. What does the term "amphoteric "mean? (1 mark) 3. Read solubility rules of metal chlorides before coming to the lab. TOTAL = 7 marks
