What Is a Basic Salt?

Alkaline refers to the ability of a substance to provide unshared electron pairs to other substances in a solvent. At normal temperature, when the pH is> 7, the solution is alkaline.

[jin xìng]

For a substance, its basicity depends on the unpaired electron acceptance

Alkaline substances: baking soda for bread, household cleaners ... persimmons and soaps contain alkaline substances. (See the second unit of the science book in the sixth grade of the Soviet Education Edition. Text: "

Alkalinity in magmatic rocks has nothing to do with pH. The basic indicator used is the Ritman index. The calculation formula is = (K2O + Na2O) 2 / (SiO2-43). The content of Na2O + K2O in magma is called the total alkali content. Because of their significant differences in the mantle and crust, they are the most easily meltable components of the main elements, and are sensitive to changes in the composition of the source area, the degree of partial melting, and the evolution of the magma. Significant. ^[1]
