What is Ammonium Carbonate Like?
Ammonium carbonate is a white, solid material. It can easily dissolve in water, just like sugar or salt. It has a faint smell, a bit like ammonia.
When it mixes with acids, it creates something new. It forms an ammonium salt and carbon dioxide gas. This gas is the same one we breathe out! If it reacts with bases, it releases ammonia gas.
How is Ammonium Carbonate Made?
Scientists make ammonium carbonate in a few ways. One common method involves heating certain chemicals together. These chemicals are ammonium sulfate, ammonium chloride, and calcium carbonate. They are heated in a special oven called a furnace.
After this process, the ammonium carbonate is left out in the air. This helps to break down any extra bicarbonate. Then, it is ready to be used. Another way to make it is by mixing carbon dioxide gas with ammonia.
What is Ammonium Carbonate Used For?
Ammonium carbonate has some interesting uses. One of its main jobs is in baking. It helps bread and other baked goods to rise. This is why it's called "baker's ammonia." When heated, it breaks down and releases gas, making the dough light and fluffy.
It can also be found in some cough syrups. It helps to loosen mucus and make it easier to cough up.
