Question

Write the formula for each of the following compounds. (a) chloric acid (b) periodic acid (c) hypobromous acid (d) hrdriodic acid

Short answer

Question: Write the chemical formula for each of the following compounds: (a) Chloric Acid, (b) Periodic Acid, (c) Hypobromous Acid, (d) Hydroiodic Acid. Answer: (a) HClO₃, (b) HIO₄, (c) HBrO, (d) HI

Step-by-step solution

(a) Chloric Acid

Chloric acid is composed of hydrogen (H), chlorine (Cl), and oxygen (O). It is an oxyacid, and the name "chloric" suggests that it contains the chlorate anion (ClO₃⁻). In an oxyacid, hydrogen is bonded to an oxyanion. We know that there's one hydrogen atom, so the chloric acid formula will be HClO₃.

(b) Periodic Acid

Periodic acid is composed of hydrogen (H), iodine (I), and oxygen (O). The name "periodic" indicates that it contains the periodate anion (IO₄⁻), which is an oxyanion of iodine. Since there is one hydrogen atom in the compound, the formula for periodic acid will be HIO₄.

(c) Hypobromous Acid

Hypobromous acid consists of hydrogen (H), bromine (Br), and oxygen (O). The name "hypobromous" means that it contains an oxyanion with one fewer oxygen atom than the bromite ion, so it contains the hypobromite anion (BrO⁻). Therefore, the formula for hypobromous acid is HBrO.

(d) Hydroiodic Acid

Hydroiodic acid is a binary acid made of hydrogen (H) and iodine (I) with a single bond between these elements. Since hydroiodic acid only contains one hydrogen atom and one iodine atom, the chemical formula is HI.
