Duration 20 minutes
Task
1. (a) Use the electronic balance method to complete these equations.
(i) H2SO4 + HI → S + I2 + H2O
(ii) HBr + H2SO4 → Br2 + SO2 + H2O
(iii) V3+ + I2 + H2O → VO2+ + I–
+ H+
2. Identify the anode and cathode products during the electrolysis of aqueous Na2SO4
solution.
3. (a) Describe the acid–base nature of the solutions obtained when the following compounds
are added to water. Use equations to illustrate your answers.
(i) sodium chloride
(ii) sulfur trioxide
(iii) sodium oxide
(b) (i) Write an equation for the reaction of magnesium with cold water.
(ii) Predict and explain the pH of the resulting solution.
