This information is incorrect - it should have been based on a lye.

pH > 7

KOH   - Potassium Hydroxide
NaOH  - Sodium Hydroxide
CaOH  - Calcium Hydroxide
NH4OH - Ammonium Hydroxide

pH < 7

Actually anything (inorganic at least) starting with hydrogen should be
an acid.

Hydrogen Sulphate - H2SO4
Hydrogen Chloride - HCl
Hydrogen Nitrate  - HNO3

All quite cheap to buy, but they'll burn a hole in your pocket (and keep
going) if you let them.

Fortunately H-OH just cancels out to a nice neutral pH of exactly 7....
