Calcium gluconate is a calcium salt of gluconic acid. Among chemists, it is best known as an antidote for hydrofluoric acid exposure.
Contents
Properties
Physical
White powder, moderately soluble in cold water, readily soluble in hot water.
Chemical
Heating causes calcium gluconate to decompose, liberating a large amount of carbon. This makes it a good candidate for a "Pharaoh's Serpent" experiment.
Availability and Uses
In some countries, such as the former Soviet bloc, calcium gluconate is available very cheaply in any drugstore in form of tablets or solutions. Tableted calcium gluconate can easily be purified by recrystallization through hot water.
Its main medical use is as a calcium supplement. Chemists use it as an antidote for hydrofluoric acid poisoning, in forms of topical creamy gel or injections.
Projects
- Pharaoh's Snake
- Protect yourself while experimenting with hydrofluoric acid
Handling
Safety
Calcium gluconate is harmless.
Storage
Dry calcium gluconate or a solution thereof can be stored in any container under normal conditions.
Disposal
Calcium gluconate can be disposed of into the ground or drain safely.
