Practice Acid in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A substance that donates \text{H}^+ ions (protons) when dissolved in water, increasing the hydrogen ion concentration and lowering the pH below 7. Under the Bronsted-Lowry definition, any proton donor is an acid.
Sour-tasting substances that can 'burn'—they give away hydrogen ions.
Example 1
easyAccording to the Arrhenius definition, what makes a substance an acid? Give two examples.
Example 2
mediumDistinguish between a strong acid and a weak acid. Give an example of each.
Example 3
easyName three common strong acids.
Example 4
easyWhat particle does an acid donate in solution, and how does that affect the hydrogen-ion concentration of the solution?
