Question

difference between universal indicators and pH paper

Answer 1

Both are pH indicators, however, universal indicator paper shows wether die material is acid or alkaline or neutral and gives you the exact ph-value (normally there is a scale to look at), whereas litmus paper is used to test materials solely for acidity.

Answer 2

Answer:

The range of pH is between the pH 0 to pH 14 scale, in which below pH 07 is considered as acidic, above pH 07-14 is considered basic and pH 07 is neutral, it depends on the concentration of hydrogen ions which present in the substance. Generally, the blue litmus paper, red litmus paper, pH paper, universal indicators, and pH meter are used to determine the pH. The pH paper is an indicator that changes as per the substance, in which it is dipped, Although a universal indicator is a liquid/solution substance that is dropped into a sample and it changes the substance as per to the pH (acidic or basic).

The major difference between the pH paper and universal indicator is the pH paper gives the exact pH of the substance, whereas the universal indicator used to find out the major difference between the pH paper and universal indicator is the pH paper gives the exact pH of the substance, whereas the universal indicator used to find out whether it is acid or alkaline or neutral.
