The percentage of copper in a copper(II) salt can be determined by using a thiosulphate titration. 0.305 gm of a copper(II) salt was dissolved in water and added to, an excess of potassium iodide solution liberating iodine according to the following equation
 2Cu2 (aq) + 4I (aq)   2CuI(s) + I2(aq)
The iodine liberated required 24.5cm3 of a 0.100 mole dm-3 solution of sodium thiosulphate
2S2032- (aq) + I2(aq) → 2I (aq) + S4062- (aq)
the percentage of copper, by mass in the copper (ll) salt is. [Atomic mass of copper = 63.5]
  • a)
    64.2
  • b)
    51.0            
  • c)
