Strong and Weak Acids/Bases
Are there indicators of a strong and weak acid or base based on their molecular composition or is it something that you just have to memorize as common knowledge? Any suggestions on ways that could help you memories them?

Strong Acids are usually completely ionized in solution, that is also the assumption we use for calculations.

A strong acid is one that ionizes (dissociates) entirely in a solution.
Hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid are strong acids.

Re: Strong and Weak Acids/Bases
Unfortunately, I think it's just a memorization thing in order to figure out what counts as a strong or a weak acid/base. Molecular geometry may play a role in some capacity (smaller atoms in the molecules means higher attraction, which equals less dissociation and weaker acid/base) but other than that, I'm sure there's a list out there that has all of them.

Re: Strong and Weak Acids/Bases
Any acid that dissolves 100% in water is a strong acid, otherwise it would be a weak one.
