Conjugate base

[Rachel-Weisz3C]

How can you tell if something is a conjugate base? Any info about conjugate bases would be helpful!

[Jonas Talandis]

A conjugate base is any molecule that is conjugate to the original acid from the equation. In a reaction with an acid, the conjugate base is whatever molecule is made after the acid donates its proton or loses an H.

[Charles Gu 1D]

If an acid is strong, the conjugate base will be weak and vice versa.

Conjugate bases are what remain when an acid donates a proton. In a reaction, you can spot them because they are often negatively charged because they have donated a proton during the reaction. For example, formic acid, HCOOH, has a conjugate base of HCO2- (the H+ is removed from the carboxyl group in carboxylic acids).

acid+base-->conj. base+ conj. acid. The conjugate base is an anion so that will help you identify it.

[tierra parker 1J]

the conjugate base comes from an acid after it loses the proton, ie sulfuric acid H2SO4 its conjugate base is HSO4-

[Phan Tran 1K]

If the reaction is in water, then whatever molecule that isn't the hydronium or hydroxide ion is the conjugate acid/base, depending on whether the molecule before the reaction is an acid or a base. Acids have conjugate bases and bases have conjugate acids.

Also usually carry a negative charge because they were just deprotonated.
