Question

some liquid antacids contain suspensions of aluminum hydroxide [AL(OH)3]. write a balanced equation for the reaction of AL(OH)3 with the HCI in stomach acid. include the phase of each substance.

Answer 1

The balanced equation for the reaction is:
Al(OH)₃(s) + 3 HCl(aq) → AlCl₃(aq) + 3 H₂O(l)

Answer 2

Liquid antacids contain suspensions of bases like aluminum hydroxide and magnesium hydroxide. These are usually the bases that can neutralize the stomach acids.

The chemical equation representing the neutralization reaction of stomach acid, HCl and antacid, aluminum hydroxide: Three moles of hydrochloric acid reacts with one mole aluminum hydroxide to give the salt, aluminum chloride and three moles of water.

`3 HCl (aq) + Al(OH)_(3)(aq)-->AlCl_(3)(aq) + 3 H_(2)O(l)`
