The easiest way is to use a pH meter. Dip it into the solution and read off the answer.
If you don't have a pH meter than it gets harder.
Colored indicators on paper strips can give you a rough idea of the pH by the color they turn when dipped in the solution. The same sort of dyes can be obtained in liquid form as well.
If you want to get an accurate pH and you don't have a pH meter you can use a process called titration, where you compare your solution with a solution with a known pH. Its slow, its complicated. Buy a meter.
Universal Indicator would give an aproximation but for acurate data you should use Methyl Yellow or Methyl Red
Using a calibrated pH-meter with correction for temperature and slope.
Litmus papers can only be used to determine whether the solution is acidic or basic. But from pH meter, the pH range of the solution can be determined.
The pH of a neutral solution is 7 and the concentration of H+ or H3O+ in the solution would be 1.0 X 10-7.
pH is the acidity. low pH is more acid, while high pH is more basic.
NaOH is a base so it will produce a pH above 7.
To determine if the property is an Acid the solution must be less than pH 7. and to determine if the property is a Base the solution must be greater than pH 7.
You can use a pH-paper.
You need to determine the percent of hydrogen (pH) molecules in the solution.
The easiest way to determine the pH of a solution is to use a pH meter.

The nature of the solution be it acidic or basic will determine the PH value of the given solution.
Using a calibrated pH-meter with correction for temperature and slope.
The acidity of a solution. It can either be acidic, or basic.
Neutral solution: pH =7Acidic solution: pH7.
