If hydrogen electrons dipped in two solutions of pH = 3 and pH = 6 are connected by a salt bridge, the emf of the resulting cell is

Step-by-step solution

For the solution one pH = 3 :- pH = - log H + H + =   10 - pH = 10 - 3 For the second solution pH = 6 :- pH = - log H + H + =   10 - pH = 10 - 6 According to the nernest equation :- E cell = E ° Cell - 0 . 0591 n log Oxidation Reduction E cell = E ° cell - 0 . 0591 1 log 10 - 3 10 - 6 E cell = 0 + 0 . 059 × 3 = 0 . 177 Hence, If hydrogen electrons dipped in two solutions of pH = 3 and pH = 6 are connected by a salt bridge, the emf of the resulting cell is 0 . 177   V .
