Every Ka is for a reaction HA (aq) + H2O (l) ⇄ H3O+ (aq) + A‒ (aq).
Write the chemical equilibrium for the acid H2CO3 for which the equilibrium constant is the Ka of carbonic acid.
b) Write the expression for the Ka for the reaction of carbonic acid with water.
c) If the patient’s pH is 7.30, calculate [H3O+]
