1.	On electrolysis of aq NaCl solution ,H_(2)(g), Cl_(2)(g)and NaOH are produced : 2Cl^(-)(aq)+2H_(2)Orarr2OH^(-)(aq)+H_(2)(g)+Cl_(2)(g) 62 % efficient 25 A electricity is passed through 20L 20 % NaCl solution . ( i ) Write the electrode reactions ( ii ) How much time will it take to produce 1 kgCl_(2)( iii ) What will be the molarity at that time with respect to OH^(-)? ( suppose no volume change occurs during electrolysis )
Answer» SOLUTION :`Q=Ixxtxx0.62=2718309.86""THEREFORE t=48.715h.`
