POST-LAB QUESTIONS:Part 2: Examining Physical Changes

1. Describe in detail the solubility of the sand/salt mixture in water. How does this compare with the observations made of the individual substances (sand and salt separate)?

2. Once the solution has been evaporated to dryness, describe the solid remaining in the test tube and the slid in the evaporating dish. What has been accomplished during this process?

Part 3: Examining Chemical Changes1. Compare the properties of the burned magnesium to the unburned magnesium. What evidence for a

chemical reaction was present?

2. Describe the differences between the burned and unburned magnesium when adding 6M HCI. Which test tube underwent a chemical change? What evidence for a chemical reaction was present?

3. Describe in detail the differences in solubility between heated and non-heated sucrose. What evidence of a chemical reaction was present?

4. When reacting sodium bicarbonate with HCI, what evidence for a chemical reaction was observed?
