The formula for the bromate ion is BrO₃^-.What is the formula for the bromite ion?

Question

Quizplus · Accepted Answer

To determine the formula of the bromite ion, we need to look at the charge of the bromate ion (-1) and compare it to the charge of the bromite ion. The bromate ion has one more oxygen atom than the bromite ion, so we can remove one oxygen atom and adjust the charge accordingly. Therefore, the formula for the bromite ion should be BrO2^- (one less oxygen means -2 charge instead of -1). Among the choices given, only option B has the correct formula of BrO2^- with the correct number of atoms and charges.
