Ammonia solution is a liquid mixture of ammonia salts and water and has the chemical formula NH4OH. It is also known as ammonium hydroxide, aqueous ammonia, ammoniacal liquor and ammonia water. As the concentration of dissolved ammonia increases, so the solution decreases in density
Buffer capsules are used for preparation of phosphate buffer solutions with stable pH, buffer capacity and low temperature coefficients. Buffer capsules are easy to use and dissolve easily. After that the pH value is automatically set at the necessary level.
Cobalt nitrate is the inorganic compound with the formula Co(NO3)2xH2O. It is cobalt(II)’s salt. The most common form is the hexahydrate Co(NO3)2·6H2O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.
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.
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.
