AlCl3. A 5.00 g impure sample of Al is dissolved completely in water; then treated with 2.00 mol L−1 HCl to evolve 6409 mL of H2 at 25.0 °C and 100 kPa.
The HCl solution is slowly added until the evolution of H2 is no longer observed.
a)Write down the balanced chemical equation for the reaction described above. Please include all phases (i.e. aq, s, l, g, etc...).
b) b)What percent (by mass) of the impure sample is Al? Assume that the impure components of the sample do not react with HCl.
