The magnitude of the change in oxidising power of the MnO−4/Mn2+ couple is x×10−4 V, if the H+ concentration is decreased from 1 M to 10−4 M at 25°C. (Assume concentration of MnO−4 and Mn2+ to be same on change in H+ concentration). The value of x is . (Round off to the nearest integer).[Given: 2.30RT/F=0.059]
