Sodium bromate is a chemical compound from the groups of compounds, and sodium bromates.

Production and representation

Sodium bromate may be represented by reacting liquid bromine with a solution of sodium hydroxide:

Thus, there remain five molecules NaBr and one molecule of sodium bromate ( NaBrO3 ).

Sodium bromate can also be obtained by dissolving sodium carbonate in water and subsequent reaction with bromine.

Properties

Sodium bromate is a colorless, odorless, hygroscopic solid which is readily soluble in water and a strong oxidizing agent. It decomposes above a temperature above 381 ° C, where oxygen is produced.

Use

Sodium bromate is used as oxidizing agents (e.g., as a bleaching agent and in textile dyeing ) and, as The piezoelectric single crystal. In combination with sodium, it is used in the gold wash.
