Which of the following is/are correct

Options

A. If the solutions pressure which is in contact with a metal rod is greater than osmotic pressure then such metal half cell behaves as anode.
B. Generally the solutions pressure tends to drive the ions into the solution.
C. If the solutions pressure which is in contact with a metal rod is lesser than the osmotic pressur then solution tries to acquire -ve charge with respect to the metal (or) such half cell behaves a cathode.
D. Solution's pressure has no contribution in deciding the nature of the electrode.

Answer

A, B, C

Explanation

A) ` P_s gt pi` Then metal behaves as anode ` pi = h xx d xx g , pi = (n)/(v)ST , pi = CST`
B) `P_(s)` tends to drive the ions into solution
C) ` P_(s) lt pi` metal behaves as cathode
