Memorizing Strong and Weak Acids and Bases

Postby nithika karthikeyan 3H » Tue Jan 30, 2024 5:14 pm

Are we expected to memorize strong acids and bases and assume anything that is not part of those are weak?

You are not expected to memorize them. If we are given a problem and there's a Ka or Kb value, it probably means it's weak because it doesn't dissociate completely. If there's no Ka value given it's probably a strong acid or base because then you can just assume that it dissociates completely.

It would be helpful to memorize strong bases/acids and weak bases/acids, especially for problems that may require determining the acidity/basicity/neutrality of a salt in a neutralization reaction.

The professor provides a list of Strong and weak acids and bases on the website which states that we are expected to know them. However, if a TA has said otherwise hopefully that's true!
