What is the mechanism of action for antacids?
Do they all antacids have the same efficacy?

Explore: Determine the pH of Common Solutions

1. Use the table below to indicate whether an item is an acid or a base and what you predict the pH to be. We can determine these in class through measuring.

Solution	Acid or Base	Predicted pH	Actual pH
Coffee
Cola
Distilled H₂O
Detergent
Bleach
Apple Juice
Antacid Solution

2. Using the pH meter, measure the pH and validate your predictions.
