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.
Chemically, the compound is represented by the formula C6H12O6 and could be found in plants and animals in huge quantities. Its common isomers include the L-glucose and D-glucose even though the fructose (i.e. which is the keto-form) is a widely established isomeric compound.
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.
Potassium bicarbonate (KHCO3) is an inorganic compound that appears as a white solid. It is commonly used as an antacid, leavening agent in baking, and a buffering agent in various applications. It can also serve as a potassium supplement and is recognized for its role in regulating pH levels in food and agriculture.

Hydrochloric Acid 37% from Asiachemielao is a high-purity, concentrated acid ideal for industrial, research, and laboratory applications. It is essential for pH adjustments, chemical synthesis, and various analytical procedures.
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.
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.
