List of pH Value of Different Substance

Scholarship Examination in India

pH Value is a measure of how acidic or basic a chemical is when it’s in aqueous (water) solution. A neutral pH value (neither an acid nor a base) is 7. Substances with a pH greater than 7 up to 14 are considered bases. Chemicals with a pH lower than 7 down to 0 are considered acids. The closer the pH is to 0 or 14, the greater its acidity or basicity, respectively.

How to Measure pH Values:

There are multiple ways to test the pH of substances.

The simplest method is to use pH paper test strips. You can make these yourself using coffee filters and cabbage juice, use Litmus paper, or other test strips. The colour of the test strips corresponds to a pH range. Because the colour change depends on the type of indicator dye used to coat the paper, the result needs to be compared against a chart of the standard.

The most accurate method of measuring pH is by using a pH meter. pH meters are more expensive than test papers or kits and require calibration, so they are generally used in schools and labs.
