When you mix calcium hydroxide and phenolphthalein, the solution will turn pink or magenta in color. This color change indicates that the solution is basic, as calcium hydroxide is a strong base. Phenolphthalein is a pH indicator that changes color in the presence of bases.
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will gradually turn pink as the pH increases. This color change is due to the phenolphthalein molecule shifting from its colorless form in acidic conditions to its pink form in basic conditions.
What is the evidence for a shift in equilibrium's when ammonium chloride was added to the stock solution in hydroxide phenolphthalein? In: http://wiki.answers.com/Q/FAQ/2455 [Edit categories]
Sodium hydroxide in phenolphthalein solution appears as a bright pink color when the solution is basic due to the presence of hydroxide ions. Conversely, in neutral or acidic solutions, the color fades to become colorless.
The color produced when you add phenolphthalein to sodium hydroxide solution is pink or magenta. Phenolphthalein is commonly used as an acid-base indicator, turning pink in basic solutions with a pH greater than 8.
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will initially remain colorless. Once enough sodium hydroxide has been added to make the solution basic, the color will change from colorless to pink or purple, indicating the presence of hydroxide ions. Phenolphthalein is a pH indicator that changes color in the presence of a base.
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
The color is pink with phenolphthalein.

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.
Yes, sodium hydroxide would tend to decrease the color intensity of the phenolphthalein solution in an ammonia stock. Sodium hydroxide is a strong base that would react with phenolphthalein, causing it to change color from pink to colorless.
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.
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
Sodium hydroxide in phenolphthalein solution appears as a bright pink color when the solution is basic due to the presence of hydroxide ions. Conversely, in neutral or acidic solutions, the color fades to become colorless.
When caustic soda (sodium hydroxide) reacts with phenolphthalein, the solution turns pink or magenta in color. This color change indicates that the solution has become basic or alkaline.
