1. Add sulfuric acid to a beaker.

   Warm the acid gently (but don’t boil it).

   Add a small amount of magnesium oxide to the acid.

   Stir the mixture.

   Keep adding magnesium oxide until no more dissolves (it’s in excess).

   Filter the mixture using filter paper and a funnel to remove the extra magnesium oxide.
