Enter your answer in the provided box. Find the pH of a buffer that consists of 0.34 M HBrO and 0.89 M KBrO (PK, of HBrO = 8.64)

11111nata11111 [884]

Answer : The pH of buffer is 9.06.

Explanation : Given,

$pK_a=8.64$

Concentration of HBrO = 0.34 M

Concentration of KBrO = 0.89 M

Now we have to calculate the pH of buffer.

Using Henderson Hesselbach equation :

$pH=pK_a+\log \frac{[Salt]}{[Acid]}$

$pH=pK_a+\log \frac{[KBrO]}{[HBrO]}$

Now put all the given values in this expression, we get:

$pH=8.64+\log (\frac{0.89}{0.34})$

$pH=9.06$

Therefore, the pH of buffer is 9.06.
