To predict whether or not a salt will produce a solution that is acidic, basic, or neutral, we need to have memorized our strong acids and bases.
00:10
These are the acids and these are the bases.
00:14
If the salt contains an anion from a strong acid, that anion does not affect ph.
00:20
If it contains a cation from a strong base, that cation does not affect ph.
00:26
All other ions will affect ph.
00:29
Catoions typically make the solution acidic, and anions typically make the solution basic.
00:35
So the first one is kbr.
00:41
We notice that k comes from this strong base, br comes from this strong acid.
00:47
So this will result in a neutral solution where ph will be 7.

The next one is al -n -o -3...
