Question

what is litmus paper ? How will you identity distilled water, acid and base with the of litmus paper ? ​

Answer 1

Answer:

Usually, litmus paper is either red or blue. Red paper turns blue when the pH is alkaline, while blue paper turns red when the pH turns acidic. While litmus paper is most often used to test the pH of liquids, it can also be used to test gases if the paper is dampened with distilled water before exposure to the gas.

Answer 2

Litmus paper is a filter paper we treat with a natural-soluble dye that the lichens provide us. The piece of paper that gives the result that is referred to as litmus paper can come in use as a pH indicating tool.

• Dip red litmus paper into these three solution . One of them will change the colour of red litmus to blue , then it is a base. Out of it remaining two will not change the color of red litmus paper . So the two can be acidic or water . Now dip changed litmus (blue litmus) into remaining two , one of them will change blue litmus into red ,then it is acidic and the last one is water ( neutral).
