Synthesis of Potassium Chlorate from Chlorine Bleach and Potassium Chloride
Objective
The objective is to synthesize potassium chlorate from potassium chloride and
chlorine bleach, and then use this synthesized potassium chlorate to make “instant fire”
by mixing it with sulfuric acid and sucrose
...
It is the most common chlorate used as an
oxidizing agent, disinfectant, source of oxygen, explosives, fireworks, and a component
in pyrotechnics and chemistry demonstrations
...
Chlorate-based propellants are less susceptible to damage by water but can be
completely unstable when there is the presence of sulfur or phosphorus
...
2KClO (s) + heat → 2KCl(s) + 3O (g)
Sucrose is an easy-to-oxidize energy source and burns in the presence of
oxygen
...
For the experiment,
granulated table is sugar is preferable to powdered sugar because powdered sugar can
smother the fire
...
Potassium chloride is sold as a “sodium-free”
salt substitute
...
Boiling is required for the reaction to work
...
Once crystals form,
it is removed from the heat and allowed to cool
...
3 NaClO → 2NaCl + NaClO
A saturated solution of potassium chloride is prepared in a separate container by
stirring potassium chloride into water until no more will dissolve
...
Potassium chlorate will precipitate out, leaving just the sodium
chloride in the solution
...
KCl + NaClO → NaCl + KClO
The solution is cooled in an ice bath to increase the yield of potassium chlorate
...
