What is the colour of phenolphthalein? What is the colour of phenolphthalein solution in acid solution? What is the colour of phenolphthalein solution in basic solution?
Answers
Answer:
PLS make my answer brilliant PLS
Explanation:
Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. It belongs to the class of dyes known as phthalein dyes.
Answer:
People know the terms acid or base (acidic or alkaline) from common household things. But, the function of the pH indicator is far advanced. Furthermore one of the pH testers is Phenolphthalein, which is usually colorless but on coming in contact with aid or base changes its color from pink (acidic) to purple (base).
Explanation:
It is an organic compound that we use as an acid or base indicator. Furthermore, the compound is pinkish in basic solution and colorless in acidic solution.
Besides, it’s chemical formula is C20H14O4. It means that it contains 20 carbon atoms, 14 hydrogen atom, and 4 oxygen atoms.
Most noteworthy, it does not dissolve very well in water so usually, alcohol titration is used to prepare this solution. Moreover, when you add a drop of acidic indicator in acid you sometimes see a white cloud generate in it.
Phenolphthalein
This is a precipitate of solid Phenolphthalein that forms as a result of high local concentrates, which exceeding the solubility product. Besides, it disappears when you shake the solution.
Furthermore, it turns pink when it comes in contact with a substance of a pH of 8.2 and becomes purple at an even higher pH. Moreover, this change in color is a result of ionization; that alter the charge and shape of Phenolphthalein molecule.
Besides, on exposure to the alkaline substance, they produce a pink to purple shade or hue.
