Memorizing Acids and Bases

Postby Tasnia Haider 1E » Sun Dec 03, 2017 6:49 pm

Do we have to memorize the list of weak acids and bases, and strong acids and bases for the final?

I think it would be helpful to know for the final in order to know which method to use to find the pH, since strong acids completely disassociate and weak acids only partially disassociate.

We will need to memorize which acids and bases are strong. I would assume other bases and acids that aren't "strong" are weak

I think it's important just to know the trends on the periodic table, which will help you determine which acids/bases are strong. For example, group 1 and group 2 hydroxides are generally strong bases. In addition, we learned that as the atomic radius increases (weaker bonds), it's easier for acids to give up an H+ (making it a stronger acid), which is why acid strength ranges from HF<HCl<HBr<HI.

I think it would probably be helpful to know the "strong six" (HCl, HBr, HI, HNO₃, H₂SO₄, HClO₄) for acids, and the rules for strong bases (Group 1 Hydroxides, Group 1&2 Oxides).

Even if we don't "have" to memorize strong acids and bases, I'm sure it will help with comfortability on final problems.

Are there any exceptions to the trends on the periodic table for Ch.17?

We should probably know the common strong and weak acids and bases, but otherwise there are ways we could determine the strength, such as a the presence of higher electronegative elements to offset charge or the length of the bonds.
