Consider the following half cell reaction C r 2 O 7 2 − ( a q ) + 6 e − + 14 H + ( a q ) ⟶ 2 C r 3 + ( a q ) + 7 H 2 O ( l )
= 10 − 6
The pH value at which the EMF of the half cell will become zero is_ _ _ _
[Given : standard half cell reduction potentialE C r 2 O 7 2 − , H + ∕ C r 3 + ∘ = 1.33 V ,
= 0.059 V ]
