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.
Trisodium Orthophosphate is used as Solvents (for cleaning and degreasing). Trisodium Orthophosphate is used as Viscosity adjusters and cleaning additives.
The purpose of adding sodium thiosulfate is to remove the excess iodine from the reaction mixture. This is important because iodine is a strong oxidizing agent and can cause side reactions with the organic compounds in the mixture.
Hydrazine Sulphate Extrapure AR, 99.5% is a white, water-soluble salt composed of cation hydrazinium and anion bisulfate which is solid at room temperature. Hydrazine sulfate has a number of laboratory, industrial and medical uses
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.
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.
Potassium bromate, or simply called bromate, is an oxidiser used to strengthen dough and enhance its elasticity. This helps bake uniform and whitened bread. Typically 15-30 parts per million (ppm) of potassium bromate is added to dough
