The solution is colourless.
It will turn purple
When lime water (a solution of calcium hydroxide) is mixed with phenolphthalein, the solution turns pink. This occurs because phenolphthalein is a pH indicator that changes color in basic solutions. Lime water is alkaline, so it causes the phenolphthalein to shift from colorless to pink in the presence of a base.
Litmus paper would turn blue when dipped in an aqueous solution of aspirin, indicating the solution is basic. aspirin is a weak acid and when dissolved in water, it undergoes hydrolysis releasing hydroxide ions which makes the solution basic.
The solution is basic.
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
Phenolphthalein changes from colorless to pink when it reacts with an alkaline solution.
Pink. Calcium hydroxide turns phenolphthalein pink when it is in a basic solution.
The solution is colorless.
It will turn purple
Phenolphthalein is an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.
Phenolphthalein would turn pink in a borax solution, indicating the solution is basic. Borax acts as a weak base in solution and would cause phenolphthalein to change color due to its alkaline nature.
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
The solution turns pink when a drop of phenolphthalein is introduced in barium hydroxide. Phenolphthalein is a pH indicator that changes color in the presence of alkaline solutions, indicating the basic nature of barium hydroxide.
When phenolphthalein is mixed with sodium chloride solution, no color changes will occur. Phenolphthalein is a pH indicator that changes color in response to pH levels, while sodium chloride (table salt) does not significantly affect the pH of a solution.
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
Orange. It turns colourless in acids and pink in alkaline.
Phenolphthalein turns pink in a basic solution.
