Calcium Oxide reacts with water to form calcium hydroxide. 1 of 9 Calcium hydroxide (like all metal hydroxides) are? Strong alkali. 2 of 9 What else is Calcium hydroxide used for? It is also used to neutralise soils and lakes much faster than powdered limestone. 3 of 9 What is Calcium hydroxide also called? Limewater = Calcium hydroxide 4 of 9 Limewater reacts with Carbon dioxide to form? Calcium Carbonate. 5 of 9 What is used to test for Carbon dioxide? Limewater 6 of 9 What happens in this reaction? Bubbling carbon dioxide gas through limewater turns the limewater cloudy. 7 of 9 What is formed if this occurs? Calcium Carbonate solid is formed. 8 of 9 Calcium hydroxide + Carbon dioxide -> Calcium Carbonate + water 9 of 9
