The emf of the cell Pt | H₂(g) (p = 1 bar) | HA,(0.1 M) | HA₂(0.1 M), QH₂, Q | Pt is found to be 0.731 4 V at 298 K, where HA, and HA₂ are two monoprotic weak acids. Answer the following: (a) Which of the two acids is stronger? (b) How many times is it stronger? (c) If the dissociation constant of the stronger acid is 2.1 x 10 mol dm³, calculate the dissociation constant of the other. (d) What are the values of pH of the two solutions?
