Example 1

easy
According to the Arrhenius definition, what makes a substance an acid? Give two examples.

Solution

  1. 1
    An Arrhenius acid produces H+\text{H}^+ ions (protons) when dissolved in water.
  2. 2
    Example 1: HCl→H++Cl−\text{HCl} \rightarrow \text{H}^+ + \text{Cl}^- (hydrochloric acid).
  3. 3
    Example 2: H2SO4→2H++SO42−\text{H}_2\text{SO}_4 \rightarrow 2\text{H}^+ + \text{SO}_4^{2-} (sulfuric acid).

Answer

Acids produce H+ in water: HCl, H2SO4\text{Acids produce H}^+\text{ in water: HCl, H}_2\text{SO}_4
The Arrhenius definition is the simplest model for acids. The Brønsted-Lowry definition extends this to any proton donor, even in non-aqueous solvents.

About Acid

A substance that donates H+\text{H}^+ ions (protons) when dissolved in water, increasing the hydrogen ion concentration and lowering the pH below 7.
