Explanation:

pH is the negative logarithm of hydronium ion concentration present in a solution.

To calculate the pH of the solution, we use equation:

    ......(1)

To calculate the pOH of the solution, we use the equation:

pH + pOH = 14                ........(2)

We are given:

pH = 5.54

Putting values in equation 1, we get:

Now, putting values in equation 2, we get:

14 = 5.54 + pOH

pOH = 8.46

The solution is acidic in nature.

We are given:

pOH = 9.7

Putting values in equation 2, we get:

14 = 9.7 + pH

pH = 4.3

Now, putting values in equation 1, we get:

The solution is acidic in nature.

We are given:

pH = 7.0

Putting values in equation 1, we get:

Now, putting values in equation 2, we get:

14 = 7.0 + pOH

pOH = 7.0

The solution is neither acidic nor basic in nature.

We are given:

pH = 12.9

Putting values in equation 1, we get:

Now, putting values in equation 2, we get:

14 = 12.9 + pOH

pOH = 1.1

The solution is basic in nature.

We are given:

pOH = 1.2

Putting values in equation 2, we get:

14 = 1.2 + pH

pH = 12.8

Now, putting values in equation 1, we get:

The solution is basic in nature.

We are given:

Putting values in equation 1, we get:

Now, putting values in equation 2, we get:

14 = 5 + pOH

pOH = 9

The solution is acidic in nature.
