How do I classify acids and bases in chemistry?

[Prone17]

Can anyone explain to me how to determine whether a compound is a strong acid, weak acid, strong base, weak base, or amphoteric? Thanks!

For acids, compare the original compound with the deprotonated compound. Look for stabilizing effects like resonance. For select families of organic molecules, conjugation may play a part.

The only stong bases I know of are readily soluble strong electrolytes which are salts of hydroxide ions.

What is this? :

Your other descriptive information is good, but what is a salt of hydroxide ion? A base is not a salt.

 

[espen180]

For example, NaOH is a salt of a hydroxide ion. It goes into solution, dissolves into ions, and the hydroxide acts as the base.

Look at the stability of the conjugate. The more stable the conjugate, the stronger the acid or base.
