What type of chemical will neutralize stomach acid?
The safest one is magnesium carbonate. Although alkalis will neutralise acids, they will do damage to the human anatomy, so don't use alkalis. Magnesium carbonate is the active constituent of 'Alka-Seltzer' or 'Milk of Magnesia'. Magnesium carbonate is a chemical salt. Remember all carbonates react with acids to form another salt, water and carbon dioxide. The stomach acid is Hydrochloric Acid which magnesium carbonate will neutralise. Here is the equation. 2HCl + MgCO3 = MgCl2 + H2O + CO2(The burp). Calcium carbonate can be used, but the taste is very chalky.
