    • 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.
