  1. Chapter 13 / Section 2 Acids and Bases Ronak Ahmed 2012-2013

  2. Lemons contain a substance called an acid. • One property of an acid is sour taste. Why lemons have a sour taste? Do you know what is the content of a glass of lemonade? Because its acids

  3. Acids have a Sour flavor. • Acids change colors of Indicators. • Acids react with metals. • Acids conduct Electric current. Acids and their properties

  4. An acid is any compound that increase the number of hydronium ions (H3O+), when dissolved in water. • The color of the tea becomes lighter. • Because acids cause some substances to change color. What will happen if you squeeze lemon juice into tea? And why? How is a hydronium ion formed? A hydronium ions form when a hydrogen ion (H+) separates from the acid and bonds with a water molecule (H2O) to form a hydronium ion (H3O+) What is acid?
