- Thermal Decomposition of Carbonates
- Limestone consists of Calcium Carbonate
- When heated it breaks down into Calcium Oxide and Carbon Dioxide
- Carbon Dioxide gas produced can be tested by bubbling it through limewater
- Reacts with carbon dioxide to produce calcium carbonate
- Turns from clear to milky
- Reacts with carbon dioxide to produce calcium carbonate
- Some metal carbonate decompose more easily than others
- Less stable metal carbonates break down more quickly at lower temperatures
- The effect of water on calcium oxide
- Reaction between calcium oxide and water produces calcium hydroxide
- Reaction is exothermic
- Calcium hydroxide is an alkali
- Can be used to neutralise farmers' soils
- Calcium hydroxide is dissolved in water to produce limewater
- Reaction between calcium oxide and water produces calcium hydroxide
- Metal carbonates react with acids to produce CARBON DIOXIDE, A SALT AND WATER
- Limestone consists of Calcium Carbonate
