Solutions that resist change in pH when added to a strong acid or base are known as buffer solutions.
Such a solution is called as buffer solution.
For example:- CH3COOH and CH3COONa solution is a buffer solution.

sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
4.0 (APEX)
The PH paper soaks up the solution & tests the liquid, the pH paper will then change colour to show what the solution contains. Although if the paper stays the same colour it means the solution is nutral & safe.
Neutral solution: pH =7Acidic solution: pH7.
Using a pH indicator such as litmus which displays a colour change based on the pH of the solution, or using a sold state digital probe which would give a numerical result on the display.
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.

Buffer Resist and Maintains the PH of the solution if there change in the environment of the solution.
pH indicators change their color according to the pH of a solution.
A buffer is a substance in a solution that releases and captures hydrogen ions, keeping the pH the same.Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not changeA buffer resists change in pH by accepting hydrogen ions when acids are added to the solution and donating hydrogen ions when bases are added.
pH is the acidity. low pH is more acid, while high pH is more basic.
to limit the pH change in a solution
A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Normally, the indicator causes the colour of the solution to change depending on the pH.
It's easier to change the pH of a weak acid than a strong acid.
The PH paper soaks up the solution & tests the liquid, the pH paper will then change colour to show what the solution contains. Although if the paper stays the same colour it means the solution is nutral & safe.
The water solution of sodium chloride is neutral.
