Question
During the bosh process to prepare Hydrogen, some carbon dioxide is also obtained as a by-product. Write a chemical equation to remove this carbon dioxide by using caustic potash.
Hint:
A carbonate is formed a
The correct answer is:
The correct option is b)
Potassium hydroxide absorbs CO2 and SO2. Potassium hydroxide is an inorganic compound with the formula KOH, commonly referred to as caustic potash. When CO2 is absorbed by KOH, K2CO3 (potassium carbonate) is formed, which continues to dissolve in solution.
