Superconcentrated electrolytes, also known as water-in-salt or solvent-in-salt liquids, usually refer to chemical systems, which are liquid near room temperature and consist of a solvent-to-dissoved salt in a molar ratio near or smaller than ca. 4-8, i.e. where all solvent molecules are coordinated to cations, and no free solvent molecules remain.

Fluorosilicic acid (H 2 SiF 6) is the most commonly used additive for water fluoridation in the United States. [46] It is an inexpensive liquid by-product of phosphate fertilizer manufacture. [42] It comes in varying strengths, typically 23–25%; because it contains so much water, shipping can be expensive. [43]
