Commercial brass, an alloy of Zn and Cu, reacts with hydrochloric acid as follows:
Zn (s) + 2 HCl (aq) → ZnCl 2 (aq) + H2 (g) (Cu does not react with HCl.)
When 0.5065 g of a certain brass alloy is reacted with excess HCl, 0.0985 g ZnCl 2 is eventually isolated. How could this result be checked without changing the above procedure?
