Determining the Oxidation State of Bromine in Ca(BrO3)2

To determine the oxidation state of bromine in the compound Ca(BrO3)2, we can use the following information:

1. Bromine in Perbromate Ion (BrO4-) - The perbromate ion (BrO4-) has an oxidation state of +7. 2. Bromine in Bromate Ion (BrO3-) - The bromate ion (BrO3-) has an oxidation state of +5. 3. Bromine in Hypobromite Ion (BrO-) - The hypobromite ion (BrO-) has an oxidation state of +1. Based on the information provided, we can calculate the oxidation state of bromine in Ca(BrO3)2 as follows:

- The compound Ca(BrO3)2 consists of the calcium ion (Ca2+) and two bromate ions (BrO3-). - Since the overall charge of the compound must be neutral, the oxidation state of calcium is +2.

Using this information, we can calculate the oxidation state of bromine in Ca(BrO3)2:

Calculation: - The oxidation state of calcium (Ca) is +2. - Each bromate ion (BrO3-) has an oxidation state of -2 (from the oxygen atoms) and the overall charge of -1. - Therefore, the oxidation state of bromine in bromate ion (BrO3-) is +5.

Conclusion: The oxidation state of bromine in Ca(BrO3)2 is +5.

This conclusion is based on the oxidation states of the elements involved and the overall charge neutrality of the compound.
