Product Details

Students carry out a series of dramatically colorful tests while learning:
• Indicators can be acidic or basic.
• Each indicator has a specific pH range.
• Indicators can be combined to create a specific guide.

Students investigate multiple indicators to identify the pH of three unknowns and predict color changes based on the data they collect. Indicators are supplied in convenient dropper-style bottles. Includes all necessary chemicals, reproducible student handouts, detailed background information and Teacher Notes with sample data and answers to questions.

Super Value Kit is complete for 5 classes of 30 students working in pairs.
