List of PH Values of Different Substances: GK Quiz

pH 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. Here’s a list of the approximate pH of some common chemicals.

 

How to Measure pH

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 color of the test strips corresponds to a pH range. Because the color change depends on the type of indicator dye used to coat the paper, the result needs to be compared against a chart of standard.

The most accurate method of measuring pH is 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.
