(A)`Cu^(2+)` ions
(B)`H_(2)`
(C)`O_(2)`
(D) `S_(2)O_(8)^(2-)`

Select the correct answer from the list given in brackets : The ion which is discharged at the anode during the electrolysis of copper sulphate solutions using copper electrodes as anode and cathode. [Cu^(2+) , OH^(-) SO_(4)^(2-) , H^(+)]

The ion which is discharged at the anode during the electrolysis of copper sulphate solution using platinum electrode as anode and cathode [Cu^(2+) OH^(-),SO_(4)^(2-) H^(+)]

During electrolysis, O_(2)(g) is evolved at anode in

During electrolysis, O_(2)(g) is evolved at anode in

In CuSO_(4).5H_(2)O copper is coordinated to

H_(2)O_(2) can be produced by the Ammonium hydrogen sulphate. Reactions occuring in electrolytic cell. NH_(4)HSO_(4) rarr NH_(4)^(+) +H^(+) +SO_(4)^(2-) 2SO_(4)^(2-) rarr S_(2)O_(8)^(2-) +2e^(-) (Anode) 2H^(+) +2e^(-) rarr H_(2) (cathode) (NH_(4))_(2)S_(2)O_(8) +2H_(2)O rarr 2NH_(4)HSO_(4) +H_(2)O_(2) Hydrolysis of Ammonium persulphate Assume 100% yield of hydrolysis reaction. What is the current efficiency when 100 Amp current is passed for 965 sec, in order to produce 17 gm of H_(2)O_(2) .

H_(2)O_(2) can be produced by the Ammonium hydrogen sulphate. Reactions occuring in electrolytic cell. NH_(4)HSO_(4) rarr NH_(4)^(+) +H^(+) +SO_(4)^(2-) 2SO_(4)^(2-) rarr S_(2)O_(8)^(2-) +2e^(-) (Anode) 2H^(+) +2e^(-) rarr H_(2) (cathode) (NH_(4))_(2)S_(2)O_(8) +2H_(2)O rarr 2NH_(4)HSO_(4) +H_(2)O_(2) Hydrolysis of Ammonium persulphate Assume 100% yield of hydrolysis reaction. How many moles of electrons are to be passed in order to produce enough H_(2)O_(2) which when reacted with excess of KI then liberated iodine required 100 ml of centimolar Hypo solution.

H_(2)underline(S_(2))O_(8)+H_(2)O to H_(2)SO_(4)+H_(2)O_(2)

H_(2)underline(S_(2))O_(8)+H_(2)O to H_(2)SO_(4)+H_(2)O_(2)

Assume that during electrolysis of AgNO_(3) only H_(2)O is electrolyesd and O_(2) is formed at the anode as : 2H_(2)Orarr 4H^(+)+O_(2)+4e^(-) O_(2) formed at NTP due to passage of 2 amperes of current for 965 sec is :
