Final answer:
The chemical formula for hydrobromic acid is HBr(aq), and hydriodic acid is HI(aq). Other formulas include hydrosulfuric acid (H₂S(aq)) and phosphorous acid (H₃PO₃(aq)).
Step-by-step explanation:
Chemical Formulas for Acids
The chemical formula for hydrobromic acid is HBr(aq). Hydrobromic acid is a strong acid that dissociates completely in water. The 'aq' indicates that it is in aqueous solution, which is how it is commonly encountered. Like hydrobromic acid, hydriodic acid also dissociates completely in water, and its chemical formula is HI(aq).
For the other acids mentioned, the chemical formulas are as follows:
Phosphorous acid - H₃PO₃(aq)
Perchloric acid - HClO₄(aq)
Knowing these formulas is essential for understanding acid-base reactions, their ionization in water, and how to write balanced chemical equations involving these acids.
