✦ Synopsis

The emf of cells Ag AgCl, HCl(m), QH, , Q Pt. Hg Hg+% , HCl(m), QHZ , Q Pt and Pt Hz, HCl(m), QH2, Q Pt have been measured at 25°C using formamide as solvent. The standard potential of the quinhydrone electrode obtained from the above cells is 0.7151 & 04009, W7137 f O*ooO5 and 0.7140 f 04002 V respectively. The calculated mean molal activity coefficients of HCI agree fairly well with earlier reported results.
