Question

difference between pH paper and Litmus Paper

Answer 1

Litmus paper is an indicator,it can be used to determine acidic and basic solutions. It is a paper stripe. Mixture of water-soluble dyes extracted from lichens are absorbed into filter paper stripes to make litmus paper. Red litmus paper is used to test basic solutions.The papers turn blue when encountered with a basic solution. The blue litmus papers turn red when encounter with an acidic solution. The neutral litmus papers are purple in color. But in case of pH paper, it is a scale it can be used to measure the acidity or basicity in a solution. The scale has numbers from 1 to 14. pH 7 is considered as a neutral value. Pure water is said to be having pH 7. From 1-6 acids are represented.
