In three test tubes $$P, Q$$, and $$R$$ iron nails, water, oil and anhydrous calcium chloride is taken. Among these test tubes, in which test tubes corrosion of nails will not take place?

The equilibrium constant of the reaction;
$$Cu\left( s \right) +2{ Ag }^{ + }\left( aq \right) \longrightarrow { Cu }^{ 2+ }\left( aq \right) +2Ag\left( s \right) $$
$${ E }^{ o }=0.46V$$ at $$298 K$$

One Faraday is equal to:

Conductivity of a solution is  affected by:

Substance which give good conducting aqueous solution are called:

A solution of sodium sulphate in water is electrolysed using platinum electrodes. The products at cathode and anode are respectively:

I. Cathode is $$-ve$$ terminal both in electrochemical and electrolytic cells.
II. Reduction occurs at cathode both in galvanic as well as electrolytic cells.
III. Chemical change in electrolytic cell is non-spontaneous.
