Mfg. of Sodium Hydrogen Carbonate (55x90cm)
Description
The “Mfg. of Sodium Hydrogen Carbonate” (55x90 cm) educational chart typically illustrates the industrial (Solvay) process for producing sodium hydrogen carbonate (baking soda, NaHCO₃), providing clear diagrams and concise explanations for chemistry classrooms and laboratories.
Chart Features
Large, laminated multicolor chart (55x90 cm) for classroom visibility and durability.
Depicts the Solvay process, which is the main industrial method for manufacturing sodium hydrogen carbonate:
Shows major raw materials: sodium chloride (NaCl, brine), ammonia (NH₃), water (H₂O), and carbon dioxide (CO₂).
Illustrates the carbonating tower, where ammonia and CO₂ are bubbled through brine, leading to precipitation of sodium hydrogen carbonate.
Describes the cooling, filtration, and drying steps used to separate pure sodium hydrogen carbonate.
