Percent Water in a Hydrate— Student Laboratory Kit
By: The Flinn Staff
Can a dry powder actually contain water molecules? The answer is yes—when the powder in question is a hydrate! Hydrates are pure substances that contain water molecules embedded in their crystal structure. In this experiment, students heat a solid hydrate to remove the water and then calculate the percent water by measuring the mass of the solid before and after heating. From this percent water value, students identify the hydrate from a list of possible unknowns. A great intro- duction to gravimetric analysis. Includes Instructor’s Notes, extensive background material, reproducible student handouts, and all necessary crystalline hydrate samples and specialized equipment.
Complete for 30 students working in pairs.
Separation of a Mixture—
Guided-Inquiry Kit
By: The Flinn Staff
Can the components of a mixture be separated? Students discover how to separate certain mixtures in this two-part, guided-inquiry lab. A mixture is a combination of two or more pure substances. Each of these substances retains its separate chemical and physical properties. Students first examine the physical properties of salt, sand, iron, and stearic acid. Then they use their collected data to design and carry out a procedure for separating a mixture of these substances. An engaging lab in which students apply concepts such as solubility, magnetism, and filtration. Instructor’s Notes, extensive background material, and reproducible student handouts are included.
Complete for 30 students working in pairs.
