Write the total and net ionic equations for the reaction in which the antacid Al(OH)3 neutralizes the stomach acid HCl. Identify the type of reaction.
a. Identify the spectator ions in this reaction. b. What would be the advantages of using Al(OH)3 as an antacid rather than NaHCO3, which undergoes the following reaction with stomach acid?
NaHCO3(aq) + HCl(aq) →→→→ NaCl(aq) +
H₂O(l) + CO₂(g)
