The magnitude of the change in oxidising power of the MnO4−∕Mn2+ couple is x×10−4 V, if the H+concentration is decreased from 1M to 10−4M at 25∘C. (Assume concentration of MnO4−and Mn2+ to be same on change in H+concentration). The value of x is ......... (Rounded off to the nearest integer). [ Given, ‌
