Best Answer

Anything containing Magnesium carbonate.

When a human suffers from acidosis/heartburn/reflux, the stomach is making too much acid.

The stomach works at pH ~ 1 , and the acid is hydrochloric acid.

Remember 'Acid + carbonate reacts to form salt plus water plus carbon dioxide.

So anything containing magnesium CARBONATE will react with the excess stomach acid to neutralise it.

MgCO3 + 2HCl = MgCl2 + H2O + CO2.

The 'salt' is magnesium chloride ; harmless to humans.

The water dilutes the contents of the stomach.

The Carbon Dioxide gas given off is the 'burp'!!!!!!

Magnesium carbonate is a horrible chalky taste, but proprietary medicines mask this taste by adding something 'sweeter/more palatable to the taste.

NB Calcium Carbonate will do the same job, but it is chalk / limestone.

I suppose Chalk is one of the most effective. It reacts easily with acid, neutralizing it. It is readily available, and it is cheap, in other words very costeffective. It is not a dangerous compound and don't make poison in the process of neutralizing acid rain. Other minerals might be more effective (out of my knowledge) but will not be as readily available and cheap as chalk is.
