Chapter 22, Problem 15
Write the formula for each of the following compounds, and indicate the oxidation state of the halogen: (a) Bromic acid (b) Hypoiodous acid.
Verified step by step guidance1
Identify the chemical formula for bromic acid. Bromic acid is an oxoacid of bromine, and its formula is HBrO_3.
Determine the oxidation state of bromine in bromic acid. In HBrO_3, hydrogen has an oxidation state of +1, and oxygen has an oxidation state of -2. Use the formula: \( +1 + x + 3(-2) = 0 \) to solve for the oxidation state of bromine (x).
Identify the chemical formula for hypoiodous acid. Hypoiodous acid is an oxoacid of iodine, and its formula is HIO.
Determine the oxidation state of iodine in hypoiodous acid. In HIO, hydrogen has an oxidation state of +1, and oxygen has an oxidation state of -2. Use the formula: \( +1 + x + (-2) = 0 \) to solve for the oxidation state of iodine (x).
Summarize the findings: Provide the chemical formulas and the calculated oxidation states for bromic acid and hypoiodous acid.
