pH paper, or litmus paper, comes in strips that change color when it comes upon contact with a solution giving a pH reading. Each pH value has a corresponding color, which can be found on a standard pH chart.

Another advantage of pH papers is that they are easier and cheaper to use than a pH meter, and provide quick readings. pH paper also doesn’t require pre-calibration before use.

How Accurate Is pH Paper?

pH paper uses colors to indicate pH values, similar to a Galileo thermometer. pH paper is great for quick qualitative research. If you only need broad accuracy to one pH value or two, pH paper will be adequate.

Note: to obtain accurate results, someone that is not considered color-blind must read the results.
