Thymol blue is used as a pH indicator. It is insoluble in water but soluble in alcohol and dilute alkali solutions. It transit from red to yellow at pH 1.2–2.8 and from yellow to blue at pH 8.0–9.6. It is usually a component of Universal indicator.
Potassium bromide is a white crystalline powder. It is freely soluble in water; it is not soluble in acetonitrile under standard conditions.
Potassium Bromide is used in combination with copper complexes as heat stabilizer in polyamide compounds, where high thermal stability during the product’s life cycle is needed.
Buffer solution, pH 4.0 ± 0.02 is used to establish and maintain an ion activity within narrow range. It is most commonly used to establish hydrogen-ion activity for the calibration of pH meters, in analytical procedures. It is also used to maintain stability of various dosage forms.
Sodium Carbonate, Anhydrous is a water insoluble Sodium source that can easily be converted to other Sodium compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Sodium Carbonate is generally immediately available in most volumes.
It is used in the manufacture of detergents, soaps, and paper. Also used in the manufacture of water glass (sodium silicate), borax, sodium phosphate, and many other sodium compounds.
