Give reason why :
Do metal ions always get discharged at the cathode on electrolysis ?

Give reason why : Is a neutral gas other than oxygen formed at the anode during electrolysis of fused alumina ?

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^(+)]

Why does H^(+) ion always get associated with atoms or molecules ?

Why does H^(+) ion always get associated with atoms or molecules ?

The ion which is discharged at the cathode during the electrolysis of copper sulphate solutions using copper electrodes an anode and cathode ?

An aqueous electrolyte consists of the ions mentioned in the list , the ion which could be discharged most readily during electrolysis ?

Give reasons why? Alkali metals are good reducing agent.

During the electrolysis of hot aqueous solution of lead bromide (a) lead ions are discharged at cathode (b) bromine gas is liberated at cathode (c) lead is deposited at cathode (d) hydrogen gas is liberated at cathode

Give reason : Metals form positive ions.

A solution contains magnesium ions (Mg^(2+)) ,iron (II) ions (Fe^(2+)) and copper ions (Cu^(2+)) . On passing an electric current through this solution which ions will be the first to be discharged at the cathode? Write the equation for the cathode reaction
