name the products formed when a metal carbonate reacts with an acid
Answers
Answer:
metal carbonate/hydrogencarbonate+acid =water (H2O)+CO2+Metal salt.
Answer:
Explanation:
Metal carbonates such as calcium carbonate (chalk) react with acids to produce the gas carbon dioxide. This can be seen in the equation:
Metal carbonate + Acid Salt + Water + Carbon dioxide
The carbon dioxide produced can be tested for in the lab using limewater, which reacts with the carbon dioxide gas. When the limewater reacts with carbon dioxide gas it turns from colourless to milky white in colour.
The salt produced depends on the acid that is used to produce it. The table below shows the type of salts that are produced from these acids:
Acid Name Type of Salt
Hydrochloric Acid chloride
Sulfuric Acid sulfate
Nitric Acid nitrate
The name of the salts produced is better illustrated in an equation.
Hydrochloric Acid
Magnesium carbonate + Hydrochloric acid Magnesium chloride + Water + Carbon dioxideMgCO3+ 2HClMgCl2 + H2O + CO2
Sulfuric Acid
Calcium carbonate + Sulfuric acid Calcium sulfate + Water + Carbon dioxideCaCO3+ H2SO4CaSO4 + H2O + CO2
Nitric Acid
Calcium carbonate + Sulfuric acid Sodium nitrate + Water + Carbon dioxideNaCO3+ HNO3NaNO3 + H2O + CO2
