How chalk is made - material, making, used, …

The base of pastel chalks is calcium sulfate (CaSO 4 ), which is derived from gypsum (CaSO 4 -2H 2 O), an evaporite mineral formed by the deposition of ocean brine; it also occurs disseminated in limestone. Chalk and dehydrated gypsum thus have similar origins and properties. Pastels also contain clays and oils for binding, and strong pigments.

How aluminium is produced

Alumina can also be made from nepheline. Nepheline occurs in the form of apatite-nepheline rock (apatite is a calcium phosphorous oxide). The production process for making alumina from nepheline also by-produces soda, potash (a material used in construction, production of some chemicals, food industry etc.), and the rare metal gallium.

Complexometric determination of zinc - Titration

general remarks. Zinc is determined by EDTA titration in almost the same way magnesium is - in the pH 10 against Eriochrome Black T.

Potassium - Wikipedia

2020-8-20 · Potassium is a chemical element with the syol K (from Neo-Latin kalium) and atomic nuer 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives.
