The photoelectric current from Na (work function, w0 = 2.3 eV) is stopped by the output voltage of the cell Pt(s) | H2(g, 1 bar) | HCl(aq., pH = 1) || AgCl(s) | Ag(s). The pH of aq. HCl required to stop the photoelectric current from K (w0 = 2.25 eV), all other conditions remaining the same, is × 10-2 (to the nearest integer). Given: 2.303 RTF = 0.06 V; E°AgCl/Ag/Cl- = 0.22 V.
