Some people get confused between pH-paper and litmus paper. Now we are solving the mystery :
Litmus paper is an indicator which determines whether solution is acidic or basic. But pH-paper is an indicator which gives an exact value pH value of solution ranging from 0 - 14.
Litmus paper gives only two colors (red or blue) while pH paper gives wide range of colors for different pH values. pH paper gives more precise result than litmus paper.
Readings on pH paper from 1 to 6 indicates the acidic medium whereas, pH value 7 is considered as neutral value and pH value ranging from 8 to 14 describes that the solution is basic in nature.
