Memorizing the Bronsted Acids and Bases

Postby DTingey_1C » Mon Nov 25, 2019 1:48 pm

Is it necessary to memorize all of the Bronsted acids and bases that have 100% deprotonation/protonation and their molecular formulas? Thanks.

I think it will be helpful at least to know the common ones such as HCl, HBr, and NaOH because I don't think we will be told if the acid or base is strong and weak unless it's one we haven't talked about.

Also, if the equilibrium constant, Ka, is given in a problem then this indicates that a weak acid is involved. In high school, my class remembered the strong acids through the mnemonic I, Cl, Br, No, ClO, ClO, So.

It will be helpful (later on, in Chem 14B) to know all the strong acids because there are only 7 and any acid that isn't one of those 7 will automatically be weak. So when we do more acid-base equilibria that involve math, it'll be pretty useful.

Here they are:
1) HClO4 - perchloric acid
2) HClO3 - chloric acid
3) H2SO4 - sulfuric acid (HSO4- is a weak acid)
4) HI - hydroiodic acid
5) HBr - hydrobromic acid
6) HCl - hydrochloric acid
7) HNO3 - nitric acid

It is useful to know the common ones. However, in lecture Dr. Lavelle mentioned that if a problem provides you with an equilibrium constant, it is likely to be a weak acid/base. This may be helpful in making that distinction.
