after electrolysis of NaCl solution with inert electrodes for certain time period, 600 ml of solution was left which was found to be 1N in NaOH... during same time, 31.75 g of Copper was deposited in Cu voltmeter in series with electrolytic cell.calculate percentage yield of NaOH obtained?

Dear Student,

Please find below the solution to the asked query:

Equivalent mass of NaOH in 600ml of 1N NaOH = (40 g /1000 ml) x 600 ml = 24 g 

Amount of NaOH formed = (40/1000) x 600 = 24 g 

31.75 g of Cu = 1 gram equivalent of Cu.
 
Since, it is connected in series, during the same period, 1 gram equivalent of NaOH should have been formed, which is = 40 g . But the amount of NaOH obtained is only 24 g.

Hence, the %  yield = (24/40) x 100 = 60 %
