Acetate

is a salt formed by the combination of acetic acid with an alkaline, earthy, or metallic base. “Acetate” also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written...

Anion and Cation

– Anion (-) is an ion with more electrons than protons, giving it a net negative charge (since electrons are negatively charged and protons are positively charged). Cation (+) is an ion with fewer electrons than protons, giving it a positive...

Anions

– Hydrogen atom (center) contains a single proton and a single electron. Removal of the electron gives a cation (left), whereas addition of an electron gives an anion.
