Phenolphthalein is a pH indicator that turns pink in basic solutions, and colorless in acidic solutions. Normal pH of saliva ranges between 6.2 (acidic) and 7.4 (basic), with 7 being neutral pH. So, the answer is, "it depends." Is the saliva acidic, or basic?
When you mix HCl (hydrochloric acid) and phenolphthalein, the phenolphthalein will turn colorless because the strong acid protonates it, resulting in the loss of its pink color. This change in color indicates the presence of an acidic solution.
When water is added to phenolphthalein, the color remains the same, which is colorless. Phenolphthalein is typically used as an indicator in titrations with strong acid and strong base where the color change is triggered by changes in pH, not by the addition of water.
If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.
Sulfuric acid is a strong mineral acid that can react with phenolphthalein, which is a pH indicator. In the presence of sulfuric acid, phenolphthalein can turn colorless due to the acidic conditions. This color change occurs because the sulfuric acid donates protons to the phenolphthalein molecule, changing its structure and causing it to lose its pink color.
Yes, it does. In fact, saliva is used to begin the digestion process in foods like carbohydrates.
Your saliva mixes up with food particles when they reach the stomach.

Teeth
The saliva mixes with the food or drinking and the odor travels up the nasal passage in the back of the throat.

The small intestine. The mouth mashes food with the teeth and mixes it with saliva which also includes some acid compounds.
When water is added to phenolphthalein, the color remains the same, which is colorless. Phenolphthalein is typically used as an indicator in titrations with strong acid and strong base where the color change is triggered by changes in pH, not by the addition of water.
When naphthalene and phenolphthalein dissolve in ethanol it creates a crystal-like powder. The powder will also appear to have a yellow tinge and has no smell.
it turns into a pinkish red color
The effect on bread when mixed with saliva is a sweet taste which is because the saliva mixes in with the starch in the bread to make a horrible taste in your mouth if left for too long x
