The pka of hco3 - (or pka2 of h2co3) is 10.33. what is the ph of a solution that has 0.1 m na2co3 and 1.0 m nahco3?
Margarita [4]

The given solution is a mixture of NaHCO_{3}and Na_{2}CO_{3}. It acts as a buffer as it is a combination of the weak acid HCO_{3}^{-}and it's conjugate base CO_{3}^{2-}.

[Acid] = [HCO_{3}^{-}]=1.0 M

[Base] =[CO_{3}^{2-}]=0.1 M

pH of the buffer solution can be calculated from Hendersen-Hasselbalch equation as below:

pH=pK_{a}+log\frac{[CO_{3}^{2-}]}{[HCO_{3}^{-}]}

pH=10.33+log\frac{0.1}{1.0}

pH = 10.33+(-1)

     = 9.33
