Carbon dioxide gas, CO2(gas)
As carbonates are mildly basic, anything acid will react with them (releasing carbon dioxide gas).
No, any strong acid will react with carbonates.
Minerals that will bubble when treated with hydrochloric acid include carbonates such as calcite (CaCO3) and dolomite (CaMg(CO3)2. The reaction with hydrochloric acid produces carbon dioxide gas, which creates the bubbling effect.
Carbon dioxide gas is given off when an acid reacts with carbonates. This reaction forms carbonic acid, which then decomposes to release carbon dioxide gas.
Carbon Dioxide
To test water for carbonates, you can use a simple acid-base reaction method. Add a few drops of hydrochloric acid to the water sample—if carbonates are present, you will see effervescence (bubbling) due to the release of carbon dioxide gas. Another method involves using a titration technique with a standardized acid solution to determine the carbonate concentration in the water sample.
Both metal carbonates and metal hydrogen carbonates form carbon dioxide when mixed with acid.
Minerals that contain carbonate minerals, such as calcite or dolomite, will bubble when treated with hydrochloric acid due to the release of carbon dioxide gas from the reaction between the acid and the carbonate minerals. This bubbling effect is a simple test to identify carbonate minerals in mineral samples.
When you add acid to carbonates, such as calcium carbonate (CaCO3), a chemical reaction occurs. The acid reacts with the carbonate to produce carbon dioxide gas, water, and a salt. This reaction is commonly used in the neutralization of acids and in industries such as agriculture and water treatment.
When iron reacts with sulfuric acid, hydrogen gas is evolved. The word equation for this reaction is: Iron + Sulfuric acid -> Iron sulfate + Hydrogen gas. To indicate the gas evolved in the reaction, one can place a downward arrow (↓) next to the hydrogen gas in the products.
If the acid is hydrochloric acid, then the gas is hydrogen.
Yes, it is the basic property of an acid to decompose the carbonates into carbon dioxide.
