Thallium (I) chlorate is a chemical compound from the group of thallium compounds and chlorates .

Extraction and presentation

Thallium (I) chlorate can be produced by reacting thallium (I) sulfate with barium chlorate . The TlClO ₃ remains in solution, while BaSO ₄ precipitates.

${\displaystyle \mathrm {Tl_{2}SO_{4}+Ba(ClO_{3})_{2}\longrightarrow 2\ TlClO_{3}+\ BaSO_{4}\downarrow } }$

properties

Thallium (I) chlorate is a solid which is easily soluble in water. It decomposes when heated, producing chlorine compounds and thallium compounds ( thallium (III) oxide and thallium (I) chloride ).

${\displaystyle \mathrm {7\ TlClO_{3}\longrightarrow 3\ Tl_{2}O_{3}+TlCl+6\ ClO_{2}} }$

Thallium (I) chlorate is a strong oxidizing agent and, like all chlorates, must be handled with care .
