Calculate the H3O+ concentration and pH of a carbonated beverage that is .10 M in dissolved CO2- (Essentially all of the H3O+ comes from the first stage of dissociation, CO2 + 2H2O = H3O^+ + HCO3-, for which K1 = 4.4 x 10^-7)

Answer 1

H2CO3 ==> H^+ + HCO3^-

k1 = 4.4E-7 = (x)(x)/(0.1-x)
Solve for x, convert to pH.
