Litmus solution is a mixture of dyes dissolved in water.
The color change to blue, because a soap solution is a basic solution (pH greater than 7).
Sodium sulfate solution is neutral; the red litmus is purple.
Nucleation is an endothermic process.
It turn purple-blue.
Blue litmus become red in acidic solutions.
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
The Litmus solution becomes red when an acid is added in it.
turns blue
Blue litmus is turned red by an acidic solution
Blue because it contains boric acia
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.
