Abstract:
Activity coefficient of sulphuric acidin acetone-water mixture was conducted on the cell: Pt. H2(1 atm.) H2SO4(m), acetone (x%), H2O (100 – x %) Hg2 SO4. The e.m.f. was measured at eleven different molalities ranging from 0.5 to 1.00m at 32±0.05C. Standard potentials values were found by extrapolation method which were 0.5674, 0.5572, 0.5051 and 0.4654 volts at 32C for 5%, 10%, 20% and 40% acetone respectively. The mean ion activity coefficients were calculated and found to be lower than those in aqueous solutions at the corresponding molalities.
