Question

Which one of the following is the chemical formula of Hypobromous acid?
1. HBrO₄
2. HOBr
3. HBr
4. HBrO₃

Answer 1

Correct Answer - Option 2 : HOBr

The correct answer is HOBr.

• Hypobromous Acid is a weak and unstable acid.
• When bromine reacts with water hypobromous acid is formed.
  • Br₂ + H₂O ⇄ HOBr + HBr.
• Hypobromous acid is used as a deodorant, oxidizer, and bleach.
• The molecular weight of Hypobromous acid is 96.911 g/mol.

• Perbromic acid (HBrO4):​
  • Molecular Weight is 144.91 g/mol.
  • The main use of perbromic acid is as a reducing agent in the laboratory.
• Hydrogen Bromide (HBr):
  • It is also called hydrobromic acid.
  • Molecular Weight is 80.91 g/mol.
  • It is used to make other bromine chemicals and act as a chemical reagent.
• Bromic acid (HBrO3):
  • Molecular Weight is 128.91 g/mol.
  • Bromic acid is an oxoacid and only exists in the form of an aqueous solution.
