If you really want to know:

For
MAGNESIUM
Dissolve about 15 mg of the substance to be examined in 2 mL
of water R or use 2 mL of the prescribed solution. Add 1 mL of
dilute ammonia R1. A white precipitate is formed that dissolves
on addition of 1 mL of ammonium chloride solution R. Add
1 mL of disodium hydrogen phosphate solution R. A white
crystalline precipitate is formed.
