What is the main principle behind the Solvay's Process for manufacturing sodium carbonate?
- Using high pressures to dissolve sodium bicarbonate.
- Employing high temperatures to decompose sodium bicarbonate.
- Leveraging the high solubility of sodium bicarbonate in water.
- Utilizing the low solubility of sodium bicarbonate at low temperatures. (correct)
Which of the following reactions is NOT involved in the carbonation step of the Solvay Process?
Which of the following reactions is NOT involved in the carbonation step of the Solvay Process?
- CO₂(g) + NH₃(g) + H₂O(l) → NH₄HCO₃(aq)
- NH₄HCO₃(aq) + NaCl(brine) → NaHCO₃(s) + NH₄Cl(aq)
- CaCO₃(s) → CaO(s) + CO₂(g)
- NaHCO₃(s) + NaCl(brine) → Na₂CO₃(aq) + HCl(g) (correct)
What is the primary purpose of lowering the temperature in the carbonation step of the Solvay Process?
What is the primary purpose of lowering the temperature in the carbonation step of the Solvay Process?
