During a titration, the pH of an analyte solution containing HA(aq) is 3.92 and the ratio of [A–]/[HA] is 0.41. What is the Ka o
Solnce55 [7]

Answer:

Ka=4.71x10^{-4}

Explanation:

Hello there!

In this case, according to the Henderson-Hasselbach equation, it is possible to write:

pH=pKa+log(\frac{[A^-]}{[HA]} )

Next, since we are given the pH and the [A–]/[HA] ratio, we can solve for the pKa as shown below:

pKa=pH-log(\frac{[A^-]}{[HA]} )

Now, we plug in the values to obtain:

pKa=3.92-log(0.41 )\\\\pKa=3.33

Next, Ka is:

Ka=10^{-pKa}=10^{-3.33}\\\\Ka=4.71x10^{-4}

Best regards!
