Question

blue and red litmus papers are placed simultaneously in a colorless aqueous solution. it is found that the colour of both litmus papers is red. what is the nature of the solution and why?

Answer 1

if the litmus papers becomes red that means both the solutions are acidic in nature

Answer 2

When blue litmus paper is placed in a substance that is acidic, it will turn to red. However, if placed in a substance that is basic or neutral, it will remain blue. Blue litmus paper is meant to test only for an acidic pH level. When red litmus paper is placed into a basic substance, it will turn blue. If it comes in contact with an acidic or neutral substance, it will remain red. Red litmus paper is meant to test only for an alkaline pH level. Common acids include include tartar sauce, corn, bacon and beer. Hence the aqueous solution used here is Acidic in nature.
