Normal

\mathrm{Al} - \mathrm{AlC}{\mathrm{l}_3}

coupled with normal hydrogen electrode gives an e.m.f. of 1.66 V. The standard oxidation electrode potential of aluminium is :

View answer and explanation

Correct option: B

+ 1.66{\kern 1pt} {\kern 1pt} \mathrm{V}

Option B (

+ 1.66{\kern 1pt} {\kern 1pt} \mathrm{V}

) is correct because the standard oxidation potential is the negative of the standard reduction potential, and since the emf is given as 1.66 V, the oxidation potential of aluminum is +1.66 V.
