Potassium antimony tartrate is a double salt containing potassium and antimony(III) cations and tartrate anions. It has the formula K2Sb2(C4H2O6)2·3 H2O

Properties

Chemical

Addition of an acid to potassium antimony tartrate will give tartaric acid.

Physical

Potassium antimony tartrate is a white, crystalline compound that crystallizes as flat, triangular crystals.

Availability

Potassium antimony tartrate is used sometimes by biologists studying animal diets to induce vomiting in captured animals. It is available in some developing countries as a quack treatment for alcoholism and other maladies.

Preparation

Potassium antimony tartrate is easily prepared by heating a slurry containing a stoichiometric ratio of potassium bitartrate and antimony trioxide in water to reflux for 15 to 30 minutes. At this time, most if not all of the solid should have dissolved, leaving a colorless solution. The solution is then filtered to remove any remaining reactants, and cooled in the fridge or freezer. As the solution cools, white, triangular crystals of potassium antimony tartrate form. See the relevant thread for a more detailed description.

Wikipedia claims that this compound can also be made from tartaric acid and antimony trioxide, but this is clearly false, as there would be no potassium ions present.

Projects

  • Medical drug

Handling

Safety

Potassium antimony tartrate is toxic due to its antimony content, and will induce persistent vomiting if ingested.

Storage

This compound must be stored away from children and pets due to its toxicity. It may be stored with general reagents in the lab.

Disposal

Antimony compounds are toxic to the environment, and should be disposed of as hazardous waste.
