What are litmus paper?
Litmus is a natural dye indicator extracted from lichens.They react with acid (blue litmus turns red)& bases(red litmus turns blue) .Paper made with litmus dye indicators are called litmus paper and used in chemical laboratories.
What do acids and bases do to litmus paper?
An acidic solution will change blue litmus paper to red and basic solutions change red litmus paper to blue
Is paper a physical or chemical change?
Litmus is a water-soluble mixture of different dyes. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic (i.e. alkaline) conditions, with the color change occurring over the pH range 4.5 - 8.3. Neutral litmus paper is purple in color. Litmus can also be prepared as an aqueous solution that functions similarly. Under acidic conditions the solution is red, and under basic conditions the solution is blue. So the litmus paper turning blue or red is a "Chemical Change".
