Methyl Red, also called C.I. Acid Red 2, is an indicator dye that turns red in acidic solutions.
Phenolphthalein is a sensitive chemical with the formula C20H14O4 (often written as "HIn" in chemistry shorthand notation). Often used in titrations, it turns from colorless in acidic solutions to pink in basic solutions. If the concentration of indicator is particularly strong, it can appear purple. A phenolphtalein turns a bright orange color, in a solution containing a ph below 0.
Explanation:
The thickness of the frosting Moving from boron to carbon, the intensity of the bulb blank because Z increases from blank to blank. The thickness of the frosting blank because the core electron configuration is the same for both atoms. because the core electron configuration is the same for both atoms.

<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
