Question

What is an acronym or pnemonic to remember the strong bases?

Answer 1

Li ttle
Na nnies
K ill
R a b bits,
C au s ing
Ca rnivorous
S c r eaming
Ba bies

Explanation:

I never really needed a mnemonic device to help remember them...

I just always know the strong bases include all metal cations in group 1

(`"LiOH"`, `"NaOH"`, `"KOH"`, `"RbOH"`, and `"CsOH"`) (with the exception of the radioactive `"Fr"`),

and the heavy group 2 metals

(`"Ca"("OH")_2`, `"Sr"("OH")_2`, and `"Ba"("OH")_2`) (with the exception of the radioactive `"Ra"`).

If you want a mnemonic device, here's one I made up on the spot:

Li ttle
Na nnies
K ill
R a b bits,
C au s ing
Ca rnivorous
S c r eaming
Ba bies

This may sound abhorrent, but whatever it takes.
