lcium carbonate (from limestone) is heated and decomposes into calcium oxide and carbon dioxide. Calcium oxide reacts with water to form calcium hydroxide. Ammonia reacts with water to form ammonium hydroxide.
90. For over a century, sodium carbonate (often called soda ash) was made industrially by the Solvay process. This process was designed by Ernest Solvay in 1864 and was used in the United States until extensive natural sources of sodium carbonate were found in the 1970s and 1980s. Write a balanced equation, without including states, for each step in the process:
-
Calcium carbonate (from limestone) is heated and decomposes into calcium oxide and carbon dioxide.
-
Calcium oxide reacts with water to form calcium hydroxide.
-
Ammonia reacts with water to form ammonium hydroxide.
-
Ammonium hydroxide reacts with carbon dioxide to form ammonium
hydrogen carbonate.
-
Ammonium hydrogen carbonate reacts with sodium chloride to form
sodium hydrogen carbonate and ammonium chloride.
-
Sodium hydrogen carbonate is heated and decomposes into sodium
carbonate, carbon dioxide, and water.
-
Ammonium chloride reacts with calcium hydroxide to form ammonia,
calcium chloride, and water.
