With indicator papers the pH of a liquid is evaluated. Also many indicator papers are used for testing chemicals.
A litmus paper is a indicator that is used to test for acids or bases
Scientists should consider using universal pH indicator because it can provide a wide range of colors to indicate different pH levels.
Use of paper avoid the contamination of the sample.
Acids turn litmus paper red. Bases turn litmus paper blue. If the paper turns orange, its an acid.
Use universal indicator or litmus paper
Litmus paper will determine acid or base. Universal indicator paper (pH paper) will give an answer to the nearest whole number.
Indicator is a process which is used to find out the substanceis acid,base and salt. example: litmus paper and termuric both are natural indicator. example of artificial indicator: mithyl orange and phenolphtaceil
You can make a PH indicator solution out of blueberry juice, or you can buy litmus paper or use an indicator solution that you can buy at the store.
using an universal indicator, or you can use litmus paper or a pH meter.
You would have to use a special paper called litmus paper. It comes in red and blue. If a substance is a base, it will turn the red litmus paper blue. If it is an acid, it will turn the blue litmus paper red. You can also use red cabbage as an indicator, too. If you want to find the pH of a substance, use a wide-range indicator and a pH measurement.

by using an indicator like litmus paper!!!
