Carbon dioxide.

Ant-acid tablets contain magnesium carbonate.

If you wish to take one because, of acidosis/reflux/ indigestioin. Then the ant-acid tablet reacts with the excess acid in the stomach, to neutralise the acid.

The human stomach as part of the normal digestion process produces hydrochloric acid. You only know about this when you vomit(throw up/ be sick), because of that horrible burning sensation in the oesophagus, throat, and mouth.

THe magnesium carbonate reacts with hydrochloric acid to produce the salt (magnesium chloride) , water and carbons dioxide.

Here is the balanced reaction equation.

2HCl(aq) + MgCO3(aq) = MgCl2(aq) + H2O(l) + CO2(g) [ burp!!!!] .

Common chalk (CaCO3) will do the same job, but there is the horrible chalky taste on swallowing.

When antacid tablets react with acid, carbon dioxide gas is given off. This gas helps to neutralize the excess stomach acid that causes heartburn or indigestion.

What do you call the two chemicals that react together in antacid tablets?

The two chemicals that react in antacid tablets are typically aluminum hydroxide and magnesium hydroxide. These chemicals help to neutralize stomach acid and provide relief from heartburn and indigestion.


Is nitrogen given off when antacid tablets are dropped in water?

No, antacid tablets contain ingredients such as calcium carbonate or magnesium hydroxide that react with stomach acid to neutralize it. Nitrogen gas is not a byproduct of this reaction.

When you react acid with bicarbonate of soda, carbon dioxide gas is given off.


The two chemicals that react together in antacid tablets?

The two main chemicals that react in antacid tablets are typically calcium carbonate (CaCO3) and citric acid (H3C6H5O7). When these substances come into contact with stomach acid, a chemical reaction occurs that neutralizes the acid and helps alleviate symptoms of indigestion or heartburn.

What are effervescent tablets made of?

Effervescent tablets are typically made of active ingredients (such as vitamins or minerals), citric acid, sodium bicarbonate, sweeteners, and flavors. When dissolved in water, the citric acid and sodium bicarbonate react to release carbon dioxide gas, creating the fizzing effect.

This gas is given off when acid react with carbonates?

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.
