TOPIC 17: REACTIONS OF AQUEOUS SOLUTIONS

8. Three colourless solutions, A, B and C, contain potassium iodide, sodium carbonate and magnesium sulfate respectively. When barium chloride is added to solution A, the solution remains colourless. When barium chloride solution is added to B and C, a white precipitate is formed in both cases. When some dilute nitric acid is added to the precipitate in solution B, the precipitate dissolves.

Identify A, B and C. Give reasons for your choice.

(5)

9. Why are precipitation reactions, gas forming reactions and acid base reactions

described as ion exchange reactions?

(2)

10. Identify the reaction types represented in each of the following equations:

10.1 2KOH(aq) + H2SO4(aq) K2SO4(aq) + 2H2O(l) 10.2 2AgNO3(aq) + CaC2(aq) 2AgC(s) + Ca(NO3)2(aq) 10.3 2HNO3(aq) + Mg(OH)2(aq) Mg(NO3)2(aq) + 2H2O(l) 10.4 Na2CO3(aq) + 2HC(aq) 2NaC(aq) + H2O(l) + CO2(g)(8)
