Question

Henry’s law constant for carbon dioxide at 38°C is 0.00228 mol L-1 atm-1. Calculate the pH of a solution of carbon dioxide at 38°C in equilibrium with the gas at a partial pressure of 3.20 atm

Answer 1

ok so henry's law:
p= k*c
so you can now write:
c=p/k = 3,2 atm / 0,00228 mol dm-3 atm-1 = 1403,5 mol dm-3
pH = -log c = -log 1403,5 = -3,15

Answer 2

cool man thanks very much!!

Answer 3

not a problem
