A standard solution of `KNO_(3)` is used to make salt bridge, because

A

Velocity of `K^(+)` is greater than that of `No_(3)^(-)`

B

Vlocity of `NO_(3)^(-)` is greater than that of `K(+)`

C

Similar mobilities of the cation and anion diminish the liquid junction potential

D

`KNO_(3)` is insoluble in water.

Text Solution

Verified by Experts

The correct Answer is:
C
Ionic mobilities of`K^(+)` and `NO_(3)^(-)` are approximately same.

A salt bridge

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

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

Gold is used to make jewellery because

Salt bridge contains

Soft iron is used for making electromagnet because it

An aqueous solution of KNO_3 is basic due to hydrolysis

A salt bridge may contain:

Assertion (A): When an aqueous solution of KNO_(3) is electrolyzed, potassium is liberated at the cathode. Reason (R): K^(+) ions are discharged at cathode and NO_(3)^(-) at anode.

Assertion : Insert electrolytes like KCl, KNO_(3) are used in salt bridge. Reason : Salt bridge provides an electric contact between the two solutions without allowing them to mix with each other.
