Acid-Base Reactions in Solution

Why is important to know about Acid-Base reactions? Watch this clip and learn ;)
*take your time to follow some of the chemical equations shown.....pause and think about how you balanced chemical reactions in earlier tutorials.
**pause and really work through the explanation of calculations of sulphuric acid! This is a great example of conversions you did in the beginning of the unit!

Chapter 8.3 Properties of Acids and Bases

Read Chapter 8.3. Focus on the following essential questions:
- What are some general properties of acids and bases
- What are the products of neutralization?
- What are proton donors and proton acceptors?

Acids, Bases and pH

Paul Andersen explains pH as the power of hydrogen. He explains how increases in the hydronium ion (or hydrogen ion) concentration can lower the pH and create acids. He also explains how the reverse is true. An analysis of a strong acid and strong base is also included

pH and Color Change Activity

Explore how different levels of pH can be observed with a universal pH indicator. Schedule lab activity in advance with your teacher.
