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). pH =

Respuesta :

Answer : The  pH of buffer is 9.06.

Explanation : Given,

[tex]pK_a=8.64[/tex]

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 :

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

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

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

[tex]pH=8.64+\log (\frac{0.89}{0.34})[/tex]

[tex]pH=9.06[/tex]

Therefore, the pH of buffer is 9.06.
