Barium perchlorate (Ba(ClO4)2) is a powerful oxidizing agent, mainly used in pyrotechnics.

Properties

Chemical

Barium perchlorate decomposes when heated to high temperatures to liberate oxygen.

Physical

Barium perchlorate is a white solid, soluble in water.

Availability

Some fireworks may contain barium perchlorate.

Barium perchlorate can be bought from chemical suppliers.

Preparation

Can be prepared by reacting perchloric acid with barium oxide, hydroxide or carbonate. The resulting barium perchlorate solution is then concentrated and cooled to recrystallize the salt.

Another route involves the reaction between barium chloride and silver perchlorate.

Projects

  • Make flash powder

Handling

Safety

Barium perchlorate is a strong oxidizer and also toxic if ingested.

Storage

In closed bottles, away from combustible materials.

Disposal

Barium perchlorate, like other perchlorates can be reduced with elemental iron in the absence of air under UV light to barium chloride, which in term can be precipitated to barium sulfate, which has low toxicity and can be safely disposed of.
