315420 \(\mathrm{\mathrm{KCl}}\) is used in a salt bridge because :

1 It forms a good jelly with agar-agar
2 It is a strong electrolyte
3 It is a good conductor of electric current
4 The transport number of \(\mathrm{\mathrm{K}^{+}}\) and \(\mathrm{\mathrm{Cl}^{-}}\) ions are nearly same or both have same ionic mobility
CHXI08:REDOX REACTIONS

315421 Assertion :
Salts like \(\mathrm{KCl}, \mathrm{KNO}_{3}\) i.e., inert electrolytes are used in salt bridge.
Reason :
An inert electrolyte can easily be filled in the U-tube.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
