Given the measured cell potential, Ecell, is -0.3635 V at 25'C. In the following cell, calculate the H+ concentration.

Pt(s)/H2(g, 0.829 atm)/H+(aq, ?M)//Cd+2(aq,1.00M)/Cd(s)

The balanced reduction half-reactions for the cell, and their respective standard reduction potential values, E' are as followed.

2H+(aq)+2e- -> H2(g) E= 0.00V

Cd+2(aq) +2e- ->Cd(s) E= -0.403V

[H+]= ?

A pH meter employs a voltaic cell for which the cell potential is very sensitive to pH. A simple (but impractical) pH meter can be constructed by using two hydrogen electrodes: one standard hydrogen electrode and a hydrogen electrode (with 1 atm pressure of H2 gas) dipped into the solution of unknown pH. The two half-cells are connected by a salt bridge or porous glass disk. a)Write the half-cell reactions for the cell. 1) No reaction. 2) H+(aq,1M)+H2O(l)→H3O+(aq), H2(g)→2H+(aq,1M)+2e−. 3)...
