what will be the colour of the litmus in a sodium carbonate solution?

Open in App

Solution

We know that sodium carbonate is a basic salt. Hence, its aqueous solution will also be basic in nature. Since acids turn blue litmus red while bases turn red litmus blue, therefore when red litmus paper is dipped in sodium carbonate solution it will change to blue colour. Blue limus paper, however will not show any colour change and will exhibit blue colour only.
