its for my homework. I need help !! :/
they neutralise acid in the stomach for a couple of hours. Higher pH less reflux symptoms
Since you are honest and admit it for your homework (unlike a lot of people on here…)!
Antacids are alkalis and neutralize the acid. Just like your chemistry course work. Stomach acid is hydrochloric acid and a typical antacid is magnesium carbonate.
HCl + MgCO3 = MgCl + CO2 + H2O (unbalanced equation)
Antacids do not relieve anything except hyper acidity
