the reaction equation depends on the antacid used. Stomach acid is HCl, not H2SO4.
Common equations would include:
Mg(OH)2 + 2HCl --> MgCl2 + 2H2O
Al(OH)3 + 3HCl --> AlCl3 + 3H2O
NaHCO3 + HCl --> CO2 + H2O + NaCl
CaCO3 + 2HCl ---> CO2 + H2O + CaCl2
It has a chemical reaction and the antacid starts to dissolve. or When you do the white vinegar with the antacid tablets together the tube/bottle explodes and causes a chemical reaction.
no. it is a chemical reaction. and so it cannot be reversed.
How do antacid tablets work?
No. An antacid tablet dropped in water produces carbon dioxide.
No, antacid tablets do not evaporate. They are solid tablets designed to dissolve in water or in the stomach to neutralize excess stomach acid. Evaporation is the process of a liquid turning into a gas, which does not apply to solid antacid tablets.
Chemical reactions can't truly be reversed in any way. Separating the antacid tablet's contents from the water may be possible, but the material won't be a single, whole tablet again, and might not even be a single material at that point.
The reaction between antacid tablets and hydrochloric acid is classed as an acid-base reaction, and is also called a neutralisation reaction. The base or alkali in the reaction is in the antacid tablet. These reactions produce a salt (not necessarily table salt NaCl) and water.

A higher temperature generally increases the rate at which antacid tablets react with water. This is because higher temperatures cause molecules to move faster, increasing the frequency of collisions between the reactants and leading to a faster reaction rate.
Some antacid tablets may contain ingredients that react with water to produce a gas, such as carbon dioxide. However, not all antacid tablets will produce oxygen gas when added to water. It depends on the specific chemical composition of the antacid tablet.
Makes them harder to compress into tablets (and stay as tablets), and does nothing to neutralize acid.
The rate at which antacid tablets react with water generally increases with temperature. Higher temperatures provide more energy to the molecules, leading to faster movement and more frequent collisions between the antacid particles and water molecules. This enhanced interaction accelerates the dissolution process, resulting in a quicker reaction. However, extreme temperatures may also affect the stability of the active ingredients in the antacid.
