A galvanic cell consists of two hydrogen electrodes. One is in a `1.0 M H^(+)` solution and other in a solution of unknown pH. The cell potential is 0.025V. The unknown pH is

A galvanic cell is constructed of two hydrogen electrodes, one immersed in a solution with H^+ at 1M and the other in 1M KOH. Calculate E_(cell) . If 1M KOH solution is replaced by 1M NH_3 , will E_(cell) be higher or lower than in 1M KOH?

The emf of a galvanic cell composed of two hydrogen electrodes is 272mV. What is the pH of the solution in which the anode is immersed if the cathode is in a solution with a pH of 3?

A cell consists of two hydrogen electrodes. The negative electrode is in contact with a solution having pH=6. the positive electrode is in contact with a solution of pH=x. calculate the value of x if the e.m.f of the cell is found to be 0.118V at 298K
