Water

Water is an oxygen hydride consisting of an oxygen atom that is covalently bonded to two hydrogen atoms. It has a role as an amphiprotic solvent, a member of greenhouse gas, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is an oxygen hydride,

15.1: Classifications of Acids and Bases

Jan 25, 2020The significance of hydrogen was reemphasized in 1884 when Carl Axel Arrhenius defined an acid as a compound that dissolves in water to yield hydrogen cations (now recognized to be hydronium ions) and a base as a compound that dissolves in water to yield hydroxide anions. Acids and bases are common solutions that exist everywhere.

Solvent Partitioning

PM7. Acid-Base Extraction An acid-base extraction is a type of liquid-liquid extraction. It typically involves different solubility levels in water and an organic solvent. The organic solvent may be any carbon-based liqiuid that does not dissolve very well in water; common ones are ether, ethyl acetate, or dichloromethane.

Acetic acid

Glacial acetic acid is a name for water-free acetic acid. Similar to the German name Eisessig ( ice vinegar ), the name comes from the ice-like crystals that form slightly below room temperature at 16.6 C (61.9 F) (the presence of 0.1% water lowers its melting point by 0.2 C).

What is Chlorination? — Safe Drinking Water Foundation

Nov 27, 2016Of the two, hypochlorous acid is the most effective. The amount of each compound present in the water is dependent on the pH level of the water prior to addition of chlorine. At lower pH levels, the hypochlorous acid will dominate. The combination of hypochlorous acid and hypochlorite ions makes up what is called 'free chorine.'
