The standard reduction potential for the half cell `NO_j^-(aq)+2 H^+(aq)+e^- NO_2(~g)+H_2 O`is `0.78 ~V` 1). Calculate the reduction potential in ' `8 MH^*` ii) What will be the' reduction potential of the half cell in a neutral solution. "Assume all the other species to be at unit concentration.

Explanation

Using (1)
=0.78+0.059 xx 2 cdot log 10^- 7/[[log 10=1]
beginarray/l
=0.78+-7 xx 0,059 xx 2 log 10
=0.78-0.826=-0.046 ~V
endarray
endaligned
