The methanoate ion, HCO₂⁻ (aq) reacts with water to form methanoic acid and hydroxide ion, as shown in the following equation.
HCO₂⁻ (aq) + H₂0 (1) <--> H₂CO₂(aq) + OH ⁻aq)
d. Given that (OH) is 4.18 x10 Min a 0.309 M solution of sodium methanoate, calculate each of the following. Show your work and answer with correct significant digits.
(i) The value of Kb for the methanoate ion, HCO₂⁻ (aq)
(ii) The value of Ka for methanoic acid, HCO₂H
