1 A 3.80 g sample of bronze was dissolved in sulphuric acid. The copper in alloy reacted with sulphuric acid according to the equation:
Cu(s) + 2H2SO4(aq)
- CuSO4(aq) + SO2(g) + 2H2O(l)
The CuSO4 formed in the reaction was mixed with sufficient KI to produce Cul(s), 13-, and S022-
ions. The 13- ion formed in this second reaction was then titrated against thiosulphate, S2032-
solution to form I and S4062-ions.
i. Write the ionic equations for the last two reactions.
