strong v weak acids

Postby RBergtraun_3A » Mon Dec 02, 2019 10:51 pm

Do we need to know if an acid is weak or strong by heart for the test?

I think you should have a general idea of them. At least the ones he mentioned in class.

I think you really just need to know the 6 strong bases and know those are the ones that completely dissociate. The rest wouldn't completely dissociate, and it is likely that you would be given values for calculations to determine how strong or weak an acid is. Hopefully that made sense!

Would those be like the ones on Table J in the book or something else? thanks for the reply

It would be best to memorize the common strong acids and bases we talked about.

It would be a smart move to do so!

I can't find the table J you're referring to, sorry!
Also, I thought I'd just list them here. (correction: 7 strong acids and 8 strong bases)

strong acids:
HCl - hydrochloric acid
HNO3 - nitric acid
H2SO4 - sulfuric acid (HSO4- is a weak acid)
HBr - hydrobromic acid
HI - hydroiodic acid
HClO4 - perchloric acid
HClO3 - chloric acid

strong bases:
LiOH - lithium hydroxide
NaOH - sodium hydroxide
KOH - potassium hydroxide
RbOH - rubidium hydroxide
CsOH - cesium hydroxide
Ca(OH)2 - calcium hydroxide
Sr(OH)2 - strontium hydroxide
Ba(OH)2 - barium hydroxide

Thank you for this, very helpful!

I think we just should memorize the strong acids.
