Some antacid tablets contain aluminum hydroxide. The aluminum hydroxide reacts with stomach acid according to the equation: AI(OH)3 +3HCIAICI, +3H2O. Determine the moles of acid neutralized if a tablet contains 0.200 mol of Al(OH)3

Respuesta :

Answer: The moles of acid that neutralizes a tablet is 0.6 moles.

Explanation:

For the given chemical reaction between aluminium hydroxide and hydrochloric acid follows:

[tex]Al(OH)_3+3HCl\rightarrow AlCl_3+3H_2O[/tex]

By Stoichiometry of the reaction:

1 mole of aluminium hydroxide reacts with 3 moles of hydrochloric acid.

So, 0.2 moles of aluminium hydroxide will react with = [tex]\frac{3}{1}\times 0.2=0.6moles[/tex] of hydrochloric acid.

Hence, the number of moles of acid that neutralizes a tablet is 0.6 moles.
