100mL CuSO_(4)(aq) was electrolyzed using inert electrodes by passing 0.965A till the pH of the resulting solution was 1. The solution after electrollysis was neutralized, treated with excess KI and titrated with 0.04M Na_(2)S_(2)O_(3) . Volume of Na_(2)S_(2)O_(3) required was 35mL . Assuming no volume change during electrolysis, calculate: (a) duration of electrolysis if current efficiency is 80% (b) initial concentration (M) of CuSO_(4) .
100 mL of 1M AgNO_(3) solution is electrolysed using Pt electrode by passing a current of 9.65 A for 100 sec. Calcualte pH of solution after electrolysis.
500 ml CuSO_(4) solution was electrolysed using a current of 2 amp (efficiency =75%) for 60 min calculate the pH of solution at the end of electrolysis (Assume initial pH=7)
50 mL of 0.1 M CuSO_4 solution is electrolysed using Pt electrodes with a current of 0.965 ampere for a period of 1 minute. Assuming that volume of solution does not change during electrolysis, calculate [Cu^(2+)]. [H^+] and [SO_4^(2–)] after electrolysis. What will be the concentration of each species if current is passed using Cu electrodes ?
1 litre aqueous solution of NaCl was electrolysed bètweern Pt electrodes passing a direct current of 12.87 A for 100s with a current efficiency of 75%. Calculate pH of the solution after electrolysis assuming no change in volume of solution.
