Asseration : Salts like `KCl,KNO_3` i.e., inert electrolytes are used in salt bridge.
Reason : An inert electrolyte can easily be filled in the U-tube.

Text Solution

Verified by Experts

The correct Answer is:
C
Assertion is true but reason is false. Ions of inert electrolytes are not involved in any electrochemical change until they react chemically with the electrolytes in the two half-cells.

Assertion (A): A saturated solution of KCl is used in making salt bridge. Reason (R): Ionic mobilities of K^(+) and Cl^(-) are comparable.

Saturated solution of KNO_3 with agar-agar is used to make 'salt bridge' because:

Products of electrolysis depend on the nature of material being electrlysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gold), it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reaction. thus, the products of electrolysis may be different for reactive and inert electrodes. Aqueous copper sulphate solution and aqueous silver nitrate solution are electrolysed by 1 ampere current for 10 minutes in separate electrolytic cells. In these question, a statement of assertion followed by a statement of reason. choose the correct answer out of the following choices. Q. Assertion (A): At equilibrium condition E_(cell)=0 or Delta_(r)G=0 . Reason (R): E_(cell) is zero when both electrodes of the cell are of the same metal.

Assertion (A): The negative sign in the expression E_(Zn^(2+)//Zn)=-0.76 V means Zn^(2+) cannot be oxidised to Zn. Reason (R): Zn is more reactive than hydrogen & Zn will oxidised, & H^(+) will get reduced.
