The Ka value for the equilibrium reaction: H2CO3(aq) ⇌ H+(aq) + HCO3-(aq) is a measure of the strength of the weak acid H2CO3. The exact value of Ka will depend on the temperature and concentration of the solution, but for a typical solution at room temperature, the Ka value is approximately 4.3 x 10^-7.

What is the conjugate acid of HCO3- and why?

The conjugate acid of HCO3- is H2CO3 (carbonic acid). When HCO3- accepts a proton (H+), it forms H2CO3. This reaction illustrates the Bronsted-Lowry concept of conjugate acids and bases, where the base (HCO3-) accepts a proton to become its conjugate acid (H2CO3).
