WebZn (s) + 2HCl (aq) → H2(g) + ZnCl2(aq) This is one example of what is sometimes called a single replacement reaction because Zn replaces H in combination with Cl. Because some of the substances in this reaction are … WebDec 4, 2024 · If metallic zinc $\ce{Zn}$ is in contact with concentrated $\ce{HCl}$ solution, $\ce{H2}$ is produced, but the reaction is exothermic : the solution gets hot. As $\ce{HCl}$ is not so highly soluble in hot water, a fraction of the dissolved $\ce{HCl}$ will be vaporized. So the gas produced will be a mixture of $\ce{H2}$ and $\ce{HCl}$, which is not wanted.
