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.

How can you maximize the use of useful materials that you have identified?​
Bas_tet [7]

Answer: The question is not complete, here is the complete question...

How can you maximize the use of useful materials that you have identified? empty bottles, fruits peeling,old news paper

The way to maximize the use of materials identified is by identifying the 3 R's of waste management which are Reduce, Recycle and reuse .

Explanation:

For example, when we check through the materialsempty bottles, fruits peeling,old news paper them can be Reduce, Recycle and reuse.

The plastic bottles can be recycled i.e converting the waste plastic materials into another useful materials like fabric, shoes, mats.

Fruits peeling can be reuse as composts for plants. These can be allow to be decompose which serve as plant compost to release nutrients for plants growth.

Old newspapers can be reduced by been sold to junks shop and some cash can be earned from it.
