Sodium Metal (55x90cm)

The “Sodium Metal” (55x90 cm) educational chart typically depicts the properties, extraction methods, uses, and reactivity of sodium metal through well-labeled, colorful diagrams suitable for chemistry classrooms. The chart helps students understand both the industrial significance and unique behavior of sodium, an alkali metal.​

Features and Content

Printed on laminated 55x90 cm paper with multicolor illustrations and clear labels.​

Shows physical properties: silvery-white, soft, highly reactive, stored under oil to prevent oxidation.​

Outlines the production of sodium metal, primarily focusing on the electrolysis of molten sodium chloride (Downs process):

Electrolysis cell structure, electrodes, and collection of sodium at the cathode, chlorine at the anode.​

Castner process (historical), using molten sodium hydroxide.​

Chemical properties demonstrated visually:

Vigorous reaction with water to form sodium hydroxide and hydrogen gas, often depicted with flames or an explosion:

2Na(s) + 2H_2O(l) rightarrow 2NaOH(aq) + H_2(g) $$.[4][9]

Lists applications: manufacture of chemicals, sodium vapor lamps, organic synthesis, metallurgy, heat transfer, and as a laboratory reagent.​

Includes safety notes due to sodium’s high reactivity (e.g., burns violently in air/water).​

Educational Value

This chart is ideal for secondary schools and undergraduate laboratories to reinforce lessons on alkali metals, periodic table trends, and industrial chemistry. It provides a comprehensive visual guide for both conceptual understanding and process visualization.​
