The activity of H,O in 35 wt% H,SO,, measured by lowering of the vapor pressure of H,0, is 4 = 0.66 at 25 °C.27 Activities of SO?- and H* cannot be measured separately, but the mean activity AlH,0 = mµ,0YH,0 can be measured. For a salt Cm A, with cation C"+ and anion A"-, the mean activity coefficient is defined as Y± = (r" r")m+n), where y, and y_ are the individual activity coefficients. The mean activity is a thermodynamically defined, measurable quantity. For 5.5 m H,SO,, Y± = (rj-Yso?-)3 = 0.22 at 25 °C27 (as measured from galvanic cells 0.22 in the Nernst equation, along with mµ = 11.0 mol/kg and containing H, SO,). Use A,0 = 0.66 and y± = 5.5 mol/kg, to calculate the voltage of the lead-acid battery. %3| mso?- Ecell V Incorrect
