```
pH = 14 - pOH
```
Where:
- pH is the measure of acidity or basicity of a solution, ranging from 0 to 14.
- pOH is the negative logarithm of the hydroxide ion (OH-) concentration in a solution.
Given that the pOH of the substance is 4.8, we can calculate the pH as follows:
```
pH = 14 - 4.8 = 9.2
```
Therefore, the pH of the substance is 9.2, which indicates that it is a basic substance.
