Question

. Given the following pOH's, calculate the pH for the solution:

a) pOH = 4.18 b) pOH = 12.35



4. Given the following pH's, calculate the pOH for the solution:

a) pH = 6.2 b) pH = 9.55

Answer 1

Answer:

a) pH = 9.82     b) pH = 1.65

a) pOH = 7.8     b) pOH = 4.45

Explanation:

pOH + pH = 14 for all of these solutions.

Answer 2

What is pH?

pH is a quantitative measure of the acidity or basicity of aqueous or other liquid solutions.

3.a)Given;

pOH = 4.18

To Find;

pH = ?

We know that

pH + pOH = 14

pH = 14 – pOH

pH = 14 – 4.18

pH = 9.82

Thus, The pH of the solution is 9.82

b)Given;

pOH = 2.35

To Find;

pH = ?

We know that

pH + pOH = 14

pH = 14 – 2.35

pH = 14 – 2.35

pH = 11.65

Thus, The pH of the solution is 11.65

4. a)

Given;

pH = 6.2

To Find;

pOH = ?

We know that

pH + pOH = 14

pOH = 14 – pH

pOH = 14 – 6.2

pOH = 7.8

Thus, The pOH of the solution is 7.8

4. b)

Given;

pH = 9.55

To Find;

pOH = ?

We know that

pH + pOH = 14

pOH = 14 – pH

pOH = 14 – 9.55

pOH = 4.45

Thus, The pOH of the solution is 4.45
