Product Details
The reactions of alkali and alkaline earth metals with water can be spectacular reactions. Introduce the study of the periodic table and periodic trends with this exciting, but safe, small-scale demonstration of the activity of metals. Learn how elements are classified based on similarities, differences and trends in their properties, including their chemical reactions. Kit includes small, pre-cut demonstration pieces of lithium and sodium, along with magnesium ribbon and calcium turnings. Display the metals in provided Petri dishes to observe their physical properties, including color, luster, hardness and malleability, then react the metals one at a time with water. Compare the activity of each metal against the previous one to identify the periodic trends in the activity of metals.
Concepts: Alkali and alkaline earth metals, periodic table and trends, physical and chemical properties, metal activity.
Time Required: 20 minutes
Materials Provided: Five pre-cut pieces of lithium and sodium, calcium turnings, magnesium ribbon, phenolphthalein solution, disposable Petri dishes.
