when phenolphthalein is added to ammonium hydroxide the color of the final solution is pink?

Yes, when phenolphthalein is added to ammonium hydroxide (NH4OH), the color of the final solution turns pink. This is because phenolphthalein changes color in the presence of a basic medium, and ammonium hydroxide is a weak base.

Yes, when phenolphthalein is added to ammonium hydroxide (NH4OH), the color of the final solution is pink. This is because phenolphthalein is an acid-base indicator that changes color depending on the pH of the solution.

Phenolphthalein is colorless in acidic solutions (pH less than 7) and turns pink in basic solutions (pH greater than 7). Ammonium hydroxide, which is a weak base, has a pH greater than 7. When phenolphthalein is added to ammonium hydroxide, the pH of the solution increases, causing the phenolphthalein to undergo a color change from colorless to pink.

To observe this color change yourself, you can perform a simple experiment. Firstly, prepare a solution of ammonium hydroxide by adding a few drops of ammonium hydroxide solution to some water. Next, add a few drops of phenolphthalein to the solution and stir. You will notice that the solution turns pink due to the basic nature of ammonium hydroxide.
