What are salts: formation and structure

Binary, Ternary and Acid Salts. What are salts and how are they formed: explanation of the formation and structure of salts. Formulas and examples.What are salts ? Salts are chemical compounds that originate from the reaction of a hydroxide with an acid according to the generic equation: hydroxide + acid → salt + water.

Glyphosate

Glyphosate (N-phosphonomethyl glycine , C 3 H 8 NO 5 P, CAS 1071-83-6) is a broad-spectrum, non-selective herbicide developed for the elimination of weeds and shrubs, especially perennials. It is a total herbicide. It is absorbed by the leaves and not the roots . It can be applied to the leaves, injected into trunks and stems , or sprayed on stumps as a forestry herbicide. The application of glyphosate kills plants because it suppresses … Read more

Benzene

Benzene. Colorless liquid with a sweet odor. It evaporates quickly into the air and is slightly soluble in water . It is highly flammable and is formed both by natural processes and by human activities. Brief history Benzene was discovered in 1825 by the English scientist Michael Faraday , C6H6, as one of the components of an oil he collected from lighting gas pipes . Its composition … Read more
