EDTA, is a chelating agent with many applications in molecular biology. EDTA is often used in buffers as a metal ion inhibitor to maintain the stability and integrity of biological samples. EDTA binds to metal cations by forming a stable octahedral complex.

Water hardness can be measured using a procedure known as complexometric titration by adding a known concentration of the chelating agent EDTA through a burette to a sample containing an unknown amount of calcium and magnesium ions. EDTA reacts and captures these metal ions creating a larger metal complex.
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.
Diphenylamine is used for control of superficial scald in stored apples Diphenylamine is the organic compound with the formula (C6H5)2NH.
It is a colourless solid, but samples are often yellow due to oxidized impurities. It is a weak base, with a KB of 10 14. With strong acids, it forms the water soluble salt.
Calcium chloride is an a white crystalline solid at room temperature, and it is highly soluble in water.
It has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in cement.
It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. Because of its hygroscopic nature, it must be kept in tightly-sealed containers.
Zinc oxide (ZnO) is a common inorganic compound with a large number of uses. It is insoluble in water but soluble in dilute acids and bases. Its melting point is extremely high—1975 ºC, where it also decomposes. ZnO exists in two common crystalline forms: wurtzite and zincblende.
The invention relates to a method for producing calcium chloride dihydrate, which is characterized by comprising the following steps: putting hydrochloric acid (31%) and limestone powder into a reaction vat according to the mixture ratio of 2.2:1, and stirring for reaction to generate an acid calcium chloride solution; …
