Questions using arrhenius acid
Problem 1
An Arrhenius acid produces which ion when dissolved in water?
- hydrogen ion, H⁺ (as H₃O⁺)
- sodium ion, Na⁺
- chloride ion, Cl⁻
- hydroxide, OH⁻
Answer and explanation
hydrogen ion, H⁺ (as H₃O⁺)
Arrhenius acids release H⁺ ions, which combine with water to form hydronium, H₃O⁺.
