Visual Illustration of the Potassium Carbonate Production Process

The following is a textual description that illustrates the chemical reactions involved in the production of potassium carbonate.The illustration begins with the electrolytic process using potassium chloride (KCl). The potassium chloride solution is fed into an electrolytic cell.

2KCl (aq) + 2H₂O (l) → 2KOH (aq) + H₂ (g) + Cl₂ (g)

This process yields potassium hydroxide (KOH), hydrogen gas (H₂), and chlorine gas (Cl₂).The potassium hydroxide (KOH) is then reacted with carbon dioxide (CO₂).

2KOH (aq) + CO₂ (g) → K₂CO₃ (aq) + H₂O (l)

This reaction produces potassium carbonate (K₂CO₃) and water (H₂O).The potassium carbonate solution (K₂CO₃) is then concentrated by evaporation, and the resulting solution is crystallized. The crystals are then filtered, washed, and dried to produce solid potassium carbonate (K₂CO₃).The direct method, starting with potassium hydroxide (KOH), skips the electrolysis step, proceeding directly to the reaction with carbon dioxide.

2KOH (aq) + CO₂ (g) → K₂CO₃ (aq) + H₂O (l)

This reaction also produces potassium carbonate (K₂CO₃) and water (H₂O). The subsequent steps of concentration, crystallization, filtering, washing, and drying are identical.
