Alkalinity is different from basicity, which is directly related to the pH. The higher the pH, the more basic the water.Like acidity, there are different ways to measure and report alkalinity;The first is to titrate the water with acid titrant to the phenolphthalein end point. This is called the phenolphthalein alkalinity. Since phenolphthalein changes color at pH~8.3, this corresponds to a pH where all the CO32- present would be protonated.Second, acid titration to a methyl orange end point, pH~4.3, further converts the bicarbonate to aqueous carbon dioxide. At this end point, some of the weaker conjugate bases are protonated. The methyl orange end point titration indicates total alkalinity.
Yes, phenolphthalein is a compound with the molecular formula C20H14O4.
Phenolphthalein is made up of, H20, C14, O4,
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0 If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.
phenolphthalein alkalinity is due to hydroxide n carbonate salts in water...nd total alkalinity is mainly due to bicarbonate salts in water..

phenolphthalein
Phenolphthalein is made up of, H20, C14, O4,
Yes, phenolphthalein is a compound with the molecular formula C20H14O4.
The color is pink with phenolphthalein.
Phenolphthalein dissolves in water to get a clear transparent solution.
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.
In a basic medium phenolphthalein changes color frompink to colorless.
Phenolphthalein turns pink in a base and turns colourless in a base
No, phenolphthalein remains colourless in the presence of an acid.
Phenolphthalein turns pink as NaOH is a strong alkali
