How Does Zinc React With Hydrochloric Acid? | Healthfully
A metal''s ability to react with HCl depends upon the metal''s so-called activity, where metals with high activity react with HCl. Metallic zinc''s activity is high enough to allow it to react with HCl, which produces H2 gas and the compound zinc chloride, or ZnCl2, explains Dr. Martin Silberberg in his book “Chemistry: The Molecular Nature of Matter and Change. 1 "
