Compound consists of calcium, carbon and oxygen Does not dissolve in water React with acids to form calcium salt, water and carbon dioxide Decompose on strong heating to form calcium oxide(quiclime生石灰) and carbon dioxide Properties of Calcium carbonates
Calcium oxidedissolves a little water to form calcium hydroxide (slaked lime熟石灰) - plenty of heat is released - a hissing sound is produced - effervescence(起泡) occurs - calcium oxid swells and break up Properties of Calcium carbonates
Solid calcium hydroxide dissolves in water to form calcium hydroxide solution (lime water) Lime water react with carbon dioxide to form calcium carbonate and water (lime water turns chalky) Properties of Calcium carbonates
