The pH or the pOH of the different species as follows are;

a) 2.1

b) 12.7

c) 12.6

d) 5.25

e) 1.4

f) 11

e) As the temperature increases, the pH and the pOH would remain the same.

What is the pH?

The term pH of the solution has to do with the hydrogen ion concentration of thee solution. This is the measure of the degree of the acidity or the alkalinity of the solution.

In this case, we can see that we can be able to obtain the pH of the solution from the concentration of the hydrogen or the hydronium ion that has been given in the question as follows;

pH = - log[Hydrogen or hydronium ion]

Let us now answer each part of the question;

a)

pH = - log(8.2×10−3)

= 2.1

b)

pH =  - log(0.050)

= 1.3

pOH = 14 - 1.3

= 12.7

c)

pH = -log(2.5×10−13)

= 12.6

d)

pH = -log(5.6×10−6)

= 5.25

e)

pH = -log(4.3×10−2)

= 1.4

f)

If the pH is 3, the pOH is

pOH = 14 -3

= 11
