Acids & Bases

You may know something about the pH scale used to measure how strong an acid it. You've likely all heard of acid rain. Many of you might associate acids as being a little dangerous and know that you wouldn't want to spill any on yourself. Indeed some acids, and bases as well, are definitely very dangerous. However many of you will likely have already eaten or drank some acid today and splashed bases over your face and hands. And you all have a stomach full of acid right now.

Acids and bases are common substances found in many every day items, from fruit juices and soft drinks to soap. In this unit we'll exam what the properties are of acids and bases, and learn about the chemical nature of these important compounds. You'll learn what pH is and how to calculate the pH of a solution.
