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.

Ferrous Sulfate is a greenish, yellow-brown or white, odorless, crystalline (sand-like) powder. It is used in water treatment and in making other Iron compounds, and as a fertilizer and food additive.
Ferrous metals are hard, heavy, have high density, fragile, not malleable, ductile, magnetic, and rust. Non-ferrous metals are light, malleable, not magnetic, and more expensive. There are different ferrous metals, and each one has its uses. For example, steel is used in buildings, skyscrapers, and structures.
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.
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 Hydrogen Phthalate Extrapure AR, 99.9% is slightly acidic, and it is often used as a primary standard for acid–base titrations because it is solid and air-stable, making it easy to weigh accurately.
