Answer to Question #255423 in General Chemistry for Madyson

Question

Aluminum foil was immortalized in song by Weird Al Yankovic in 2014 as a parody of the popular song “Royals” by Lorde. If Weird Al used a 1.65 g sample of aluminum foil and react it with strong acid (such as 500.0 mL of hydrochloric acid at pH 0.140), he found that it liberated flammable hydrogen gas with a pressure of 0.211 atm which Weird Al collected into a 500. mL bulb at a temperature of 22.9 ^oC. How pure is the foil that Al uses to “keep his sandwich nice and fresh”? Determine whether any HCl is left over in the reaction vessel.

 

Aluminum foil (s) + HCl(aq) à Aluminum chloride (aq) + H₂ (g)

Answer 1

Yes HCl is left over in the reaction vessel.
