HBr, HClO4, KBr, and KI are all classified as strong electrolytes. This classification refers to their ability to completely dissociate into ions when dissolved in water.
Let’s break it down:
- HBr (Hydrobromic Acid): This is a strong acid that completely ionizes in water, generating H+ and Br– ions.
- HClO4 (Perchloric Acid): Another strong acid, HClO4 also fully dissociates in aqueous solution, producing H+ and ClO4– ions.
- KBr (Potassium Bromide): This is a salt that, when dissolved, separates into K+ and Br– ions, showing its property as a strong electrolyte.
- KI (Potassium Iodide): Similar to KBr, KI dissolves to yield K+ and I– ions, functioning as a strong electrolyte.
In summary, all four substances demonstrate strong electrolytic behavior in solution, making them strong electrolytes as they dissociate completely into their respective ions.
