The ratio of the volumes of H 2 evolved in these two reactions is : When zinc reacts with hydrochloric acid , zinc metal dissolves slowly to form soluble zinc chloride & hydrogen gas is evolved. Zinc oxide reacts with hydrochloric acid to form zinc chloride and water. Precautions 1. Zinc reacts with hydrochloric acid according to the reaction equation Zn (s)+2HCl (aq)--> ZnCl2 (aq) + H2(g) How many milliliters of 2.50 M HCl(aq) are required to react with 3.55 g of an ore containing 37.0% Zn(s) by mass? NaOH (d) it does not react with either dil. Chemistry-Gases. 0.129 moles Zn x (2 moles HCl / 1 mole Zn) = 0.258 moles HCl The hydrogen in $\ce{H2O}$ is covalently bonded to the oxygen, so it is difficult for the hydrogen to react. Identify the type of reaction that takes place when marble chips and zinc granules are added separately to acid taken in two test tubes. The experiment compares reactivity of three metals; magnesium, zinc and copper. You are given the following materials. 1 decade ago. Lets consider the reaction between zinc metal and hydrochloric acid as such an example. i) Marble chips ii) dilute hydrochloric acid iii) zinc granules. Since reducing agent is oxidized in a redox reaction, then zinc is the reducing agent.
