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

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.

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.

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

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.
