Litmus paper, or other pH papers can measure pH. Many pH test papers can measure specific pH values. There are also instruments called pH meters that can measure pH.
Phenolphthalein is a pH indicator commonly used in acid-base titrations. It changes color in a specific pH range (around pH 8.2 to 10), allowing the endpoint of the titration to be visually determined. This makes it easier to accurately measure the amount of titrant required to reach the equivalence point.
Phenolphthalein indicator is used in chemical experiments to determine the acidity or alkalinity of a solution by changing color based on the pH level.
No, ammonia does not turn phenolphthalein pink. Phenolphthalein is a pH indicator that turns pink in basic solutions, but ammonia is a weak base and typically does not have a strong enough pH to turn phenolphthalein pink.
Phenolphthalein is a pH indicator that changes color in response to a change in pH. When mixed with hydrochloric acid (a strong acid), phenolphthalein will turn colorless due to the decrease in pH, indicating an acidic solution.
For solutions with a pH higher than 8.2, phenolphthalein turns bright pink.
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
Phenolphthalein changes from colorless to pink in the range of pH 8.2 - 10. If toothpaste has a pH that is below this range, phenolphthalein will not indicate the basicity. if the pH is higher, which I believe it is in most (some) toothpastes, then phenolphthalein can be used, because it will turn from colorless to pink.

Phenolphthalein changes color in the pH range of approximately 8.2 to 10.0. This means that phenolphthalein starts to turn pink around pH 8.2 and turns completely pink at around pH 10.0. Since the equivalence point was at pH 7, phenolphthalein would not be the ideal indicator for this titration.

Phenolphthalein turns pink in a basic solution with a pH greater than 8.2. It is commonly used as an acid-base indicator to visually show the endpoint of a titration when the pH of the solution changes.
The pH of the solution is above 8.2. Phenolphthalein changes color from colorless to pink in the pH range of 8.2 to 10.0.
Phenolphthalein is an indicator that undergoes a colour change from colourless to pink that begins at a pH of 8.0. So in the titration your performing the phenolphthalein will start to change colour at the point when the moles of acid equal the moles of base. Although this colour change occurs at a pH of 8.0 and not at a pH of 7.0 phenolphthalein is commonly used because of the distinctive colour change that occurs. Phenolphthalein is colourless in acids and pink/purple in base. It also turns orange in very strong acids.
