1. Use BTB to classify four household products as acidic or basic. Possible substances to test include home cleaning products, glass cleaner, liquid detergent, bleach, soft drinks, liquid from food items, etc. Remember to:

State a hypothesis or purpose.
State the testing method.
Organize data in a concise table.
Read the label for each product, and list in the data table what may be the acid or base in the product.
State conclusions in terms of the hypothesis or purpose.

2. Find one common, highly colored substance that can be used as an acid-base indicator. Possible substances include fruit/vegetable juice or products, inks, food coloring, flower petals, etc. If using fresh fruit, veggies, or flowers, crush the substance with a little water or rubbing alcohol to extract the colored pigments. If red cabbage is available, it makes a superb acid-base indicator. Then use a few drops of the colored extract as the indicator. Test four more household products using the freshly made acid-base indicator. Remember to:

State a hypothesis or purpose.
State the testing method.
Use the prepared indicator to test four substances known to be acids or bases from either the LabPaq or home materials and record results.
State conclusions in terms of the hypothesis or purpose.
