Choose the stronger of each pair of acids, respectively, and explain why: a) HBrO3 or HBrO b) HBrO2 or HIO2 A. a) HBrO because Br has a lower oxidation state (fewer number of O atoms around it) in HBrO than in HBrO3; b) HIO2 because I is larger than Br B. a) HBrO3 because Br has a higher oxidation state (higher number of O atoms around it) in HBrO3 than in HBrO; b) HBrO2 because Br is more electronegative than I C. a) HBrO because Br has a lower oxidation state (fewer number of O atoms around it) in HBrO than in HBrO3; b) HBrO2 because Br is more electronegative than I D. All of these acids are very weak, so their relative strengths are similar E. a) HBrO3 because Br has a higher oxidation state (higher number of O atoms around it) in HBrO3 than in HBrO; b) HIO2 because I is larger than Br
