Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
I think it is supposed to be PURPLE. Because of the following:It turns red when placed in acidic solutionIt turns blue when placed in alkaline solutionAnd purple when placed in neutral.
It helps in indicating whether a substance is acidic or basic A red litmus paper turns blue in basic solution and turns red in acidic solution A blue litmus paper turns red in acidic solution and turns darker blue in basic solution
The solution is likely basic or alkaline. Red litmus paper turns blue in the presence of a base due to the change in pH.
In a neutral solution, both red and blue litmus paper will remain unchanged in color. Red litmus paper turns blue in basic solutions, while blue litmus paper turns red in acidic solutions.
An aqueous solution of borax will have a slightly basic pH. Litmus is a pH indicator that turns blue in basic solutions and red in acidic solutions. Therefore, when litmus is added to an aqueous solution of borax, it will likely turn blue.
Blue litmus paper turns red when grape juice is added, indicating that the solution is acidic.
Red litmus paper remains red when a neutral solution is added. This is because neutral solutions do not affect the color of red litmus paper.
Blue litmus is turned red by an acidic solution
Litmus paper turns blue in basic solution.
Litmus paper is basically used to test nature of solution i.e acid or alkaline. For acid blue litmus turns to red. But for alkaline red litmus turns to blue color.
Toothpaste solution typically turns litmus paper blue, indicating it is basic or alkaline in nature.
Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
If you mix litmus solution with an alkali, the litmus solution will turn blue. Litmus is a pH indicator that turns red in acidic solutions and blue in alkaline solutions.
an acid turns the litmus paper red.
An acid solution turns blue litmus red.
Hydrochloric acid is an acidic solution, so when litmus powder is added to it, the litmus powder would most likely turn red. This is because litmus paper turns red in acidic solutions and blue in basic solutions.
