Bromide vs. Bromate: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Bromide is a compound containing the bromine ion in a -1 oxidation state, while bromate contains bromine in a +5 oxidation state.
Key Differences
Bromide, chemically represented as Br-, is a bromine ion with a negative charge, indicating an extra electron. Bromate, with the formula BrO3-, is an oxidized form of bromine, indicating a loss of electrons. Both are derivatives of the element bromine but differ in their chemical properties.
