For instance, the p Ka value of acetic acid in DMSO is 12.3 [11], while its p Ka value in MeCN is 23.5. It means that acetic acid is 100′000′000′000 times (11 units in logarithmic scale) stronger in DMSO than in MeCN. Pyridine ( B' = 420 [8]) is a more basic solvent than both DMSO and MeCN.

Unregulated mining has the potential to severely damage the environment. It can damage soil, air, and water. Governments enforce regulations on companies to use advanced technology to meet environment-related protections. Environment licenses and social licenses are made compulsory to start and operate mines (Chen et al., 2023).

Abstract. This is a book about how the modern notion of materiality was established during the period c. 1680-1760. It studies what natural philosophers engaged in chemistry and mineralogy said about phenomena such as witchcraft, trolls and subtle matters, and relates this discourse to their innovations in matter theory.
Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.
What is an ore in chemistry? Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.
The use of calcium peroxide (CaO 2) powder as a source of H 2 O 2 to promote modified Fenton (MF) chemistry was studied. First, the rate of production and yield of H 2 O 2 from CaO 2 dissolving in water at pH 6–9, and 12–13 (i.e., unbuffered CaO 2) was measured. The rate of CaO 2 dissolution increased as pH decreased, from 62 h …
