Explain : On electrolysis in acidic solution, glycine migrates towards cathode while in alkaline solution, it migrates towards anode.

During the electrolysis of NaCl solution, the gas liberated at the anode is

In the electrolysis of aq. NaCl solution which half-cell reaction will occurs at anode

In Alkaline solution we have chromates and in acidic solution, dichromates ? Explain.

Under the influemce of an electric field, the particles in a sol migrate towards cathode. The coagulation of the same sol is studied using NaCl,Na_(2)SO_(4) , and Na_(3)PO_(4) solutions. Their coagulation values will in the order a. NaClgtNa_(2)SO_(4)gtNa_(3)PO_(4) b. Na_(2)SO_(4)gtNa_(3)PO_(4)gtNaCl c. Na_(3)PO_(4)gtNa_(2)SO_(4)gtNaCl d. Na_(2)SO_(4)gtNaClgtNa_(3)PO_(4)

Explain why an aqueous solution of sodium sulphate is neutral while an aqueous solution of sodium carbonate is basic in nature.

Explain why an aqueous solution of CuSO_4 is acidic in nature ?

During electro-osmosis of Fe(OH)_(3) sol a. Sol particles move towards anode b. Sol particles move towards cathode c. The dispersion medium move towards anode d. The sol particles do not move in either direction

A poled egg when dipped in water swells while is saturated brine solution it shrinks. Explain

which of the following statement is / are correct for electrophoresis : Colloidal are uncharged particles and do not migrate towards the electrodes when electric field is applied, In electrophoresis , sol migrates either to the anode or to the cathode depending on the positively or negatively charged sol, Electrophoresis is useful for finding the charge on a sol, all of these.

Assertion: Electrolysis of NaCl solution gives chlorine at anode instead of O_2 . Reason: Formation of oxygen at anode requires overvoltage.
