Re: Weak Acids/Bases?
Examples of weak acids - CH3COOH, H3PO4, HF
Examples of weak bases - NH3, C5H5N, NH4OH
Weak bases are only partially protonated in solution. Most of the examples of strong/weak acids and bases you just have to memorize. However, for weak acids there are a few guidelines to distinguish them, such as the length of the A-H bond and the stability of the conjugate base.

Re: Weak Acids/Bases?
I'm not too sure about bases, but acid strength is determined by bond length and stability of the anion in the compound. The longer/weaker the bond between the atoms, and the more stable the anion, the stronger the acid.
For example, HI is a stronger acid than HF because I is a larger atom than F, meaning the bond between I and H will be longer and weaker, which means it is a stronger acid.
Also, hypochlorous acid (HClO) is a stronger acid than hypoiodous acid (HOI) because Cl is more electronegative than I, therefore it is a stronger anion in the compound and results in more acidic character.

Re: Weak Acids/Bases?
You are supposed to remember all the strong acid and bases, according to a UA. Then the rest are all weak ones.

I went to Lyndon's review session and he said its best to just memorize them
