(a) The activity coefficient for H in the 0.200 M HBr solution at 25°C can be calculated using the following equation:
γH = 10^(-pH) / [H+] = 10^(-0.806) / 0.200 = 0.25
(b) The activity coefficient for H in the 0.200 M HNO3 solution at 25°C can be calculated using the following equation:
γH = 10^(-pH) / [H+] = 10^(-0.822) / 0.200 = 0.22
(a) The measured pH of a 0.200 M HBr solution at 25°C is 0.806. Calculate the activity coefficient for H .
(b) The measured pH of a 0.200 M HNO3 solution at the same temperature is 0.822. Calculate the activity coefficient for H in this solution.
