What is the ph of 0.1 m nahco3 K1=a and k2 =b for carbonic acids

Ananya Hira 28th Jul, 2026
The bicarbonate ion participates in two competing primary equilibria in an aqueous solution:
    • Acidic Dissociation:
      \(\text{HCO}_{3}^{-}\rightleftharpoons \text{H}^{+}+\text{CO}_{3}^{2-}\quad \left(K_{2}=b\right)\)
    • Basic Hydrolysis:
      \(\text{HCO}_{3}^{-}+\text{H}_{2}\text{O}\rightleftharpoons \text{H}_{2}\text{CO}_{3}+\text{OH}^{-}\quad \left(K_{b}=\frac{K_{w}}{K_{1}}=\frac{K_{w}}{a}\right)\)
