Q. The equilibrium cell potential of the galvanic cell
is found to be Ecell,eq = 1.410 V at 298.15K. The standard cell potential is Ecell,eq = 1.360V.
(a) Write the cell reaction and calculate its thermodynamic equilibrium constant at 298.15K.
(b) Use the cell measurement to calculate the mean ionic activity coefficient of aqueous HCl at 298.15K and a molality of 0.500 mol kg-1.
Q. Define the Normality of solutions? Ans. Sometime normality is used to measure concentration. Normality (abbreviated N) is the number of gram-equivalent masses of solute in 1
