Acid Rain 1 of 6 What is the test for Carbon Dioxide? Carbon dioxide turns limewater solution cloudy. 2 of 6 What is the word equation for the test for CO2? Calcium Hydroxide + Carbon Dioxide = Calcium Carbonate + Water 3 of 6 Carbonates react with acids to give which three things? A salt, water and Carbon Dioxide. 4 of 6 What happens when you add water to calcium oxide? It produces Carbon Hydroxide. 5 of 6 Describe the limestone cycle. Step 1: CaCO3 is heated and becomes CaO and CO2. 2: Water is added and CaO becomes Ca(OH)2. 3: CO2 is added and it becomes CaCO3 again. 6 of 6
