Answer:

answer is what is the pH number is that Our New account last name is Our brothers name he will be happy to

The pOH of the solution is 10.4

The pH of the solution is 3.6

Calculating pOH & pH

From the question, we are to determine the pOH and pH of the solution

pOH can be calculated by using the formula

pOH = -log[OH⁻]

From the question,

[OH⁻] = 4×10⁻¹¹ M

∴ pOH = -log(4×10⁻¹¹)

pOH = 10.4

Hence, the pOH of the solution is 10.4

Now, for the pH

Using the formula,

pH + pOH = 14

Then, we can write that

pH = 14 - pOH

∴ pH of the solution is

pH = 14 - 10.4

pH = 3.6

Hence, the pH of the solution is 3.6
