MERCURY- MERCURIC SULPHATE ELECTRODE

MERCURY-MERCURUS SULPHATE ELECTRODE

The 0.1M copper sulphate solution in which copper electrode is dipped at 25^(@)C . Calculate the electrode potential of copper electrode. [Given : E^(0) Cu^(+2)//Cu = 0.34V]

Assertion : Stannous chloride gives grey precipitate with mercuric chloride , but stannic chloride does not do so. Reason : Stannous chloride is a powerful oxidising agent which oxidises mercuric chloride to metallic mercury .
