WebMar 25, 2024 · Limestone is also called calcium carbonate. When heated strongly it forms calcium oxide (slaked lime). This calcium oxide when dissolved in water forms calcium hydroxide (lime water). If we bubble carbon dioxide through calcium hydroxide solution, it forms a milky suspension of calcium carbonate. WebCaO(s) + CO2(g) → CaCO3(s) However, above about 1200 K the opposite reaction occurs, calcium carbonate decomposes to form calcium oxide and gives off carbon dioxide. This is what happens in lime kilns where limestone (calcium carbonate) is heated to form lime (calcium oxide).
