(They take a lot of thought because there are a lot of rules. If you take the time to understand and remember these
mnemonics, they’ll save your life!! Practice writing these rules down using the mnemonics several times.)
For solubility rules:
Mnemonic #1: For Solubles
Not All Attractive Fun Cheerleaders Buy Indecent Shorts (See the Soluble column below)
The mnemonics for the exceptions are given next to the exceptions. The mnemonics vary for each exception.

Note: Just remember that alkali metals are always soluble!! They are not included in the mnemonic (too many A’s for the

)
You’ll need to come up with mnemonics yourself for the generally insolubles and insolubles (and their exceptions) as
I don’t have one.
Mnemonic #2: For Strong Acids
No Cool Cheerleaders In Chemistry Buy Indecent Shorts (See the order in which I listed the strong acids. You will need to
remember that they all have H in front with SO
having 2 H’s.)

For the bases, you’ll need to come up with a mnemonic on your own. These might be easy enough to remember
without a mnemonic?
