Q5ChemistryUnit 7: Redox Reactions and Electrochemistry

Cathodic standard reduction potential minus anodic standard reduction potential is equal to:

Q6ChemistryUnit 7: Redox Reactions and Electrochemistry

Assertion In electrochemical cell, we can not use KCl in the salt bridge if anodic or cathodic compartment consists of

\mathrm{Ag}^{+}

P b^{2+}

ion. Reason Salt bridge is employed to maintain the electrical neutrality and to minimize the liquid-liquid junction potential.
