Metal carbonates Flashcards
Metal carbonates react with…
acid to give a salt, water and carbon dioxide.
Powdered limestone is used…
to raise the pH of soils or lakes affected by acid rain.
Lime water
Used to find a presence of carbon dioxide. It turns cloudy if carbon dioxide is presented. It is calcium hydroxide.
Carbon dioxide is weakly…
acidic.
The white colour is caused by…
tiny solid particles of insoluble carbonate formed as a precipitate.
Thermal decomposition of limestone is used to make…
- to make cement
- glass
Calcium oxide is used…
to create a cheap alkali calcium hydroxide by reacting it with water.
Thermal decomposition of limestone produces…
carbon dioxide and calcium oxide.
Limestone is a…
calcium carbonate. CaCO3
Which two metal carbonates do not decompose at the temperature of bunsen burner?
Sodium and potassium carbonate, they need a higher temperature.
When lime water reacts with carbon dioxide…
it produces calcium carbonate.
