   Zinc reacts with sulfuric acid to produce hydrogen. The reaction is catalysed by copper. In this practical, students can compare the rate of reaction (with and without copper) by means of the rate of production of hydrogen gas bubbles

   Aim of this experiment to study the reaction between zinc and dilute sulphuric acid. Zinc metal reacts with dilute sulphuric acid to produce zinc sulphate and hydrogen gas. The metal displaces Hydrogen from the acid and forms a salt.

   In lesson 2, selecting zinc and sulfuric acid as the example to follow through to producing crystals of the salt is governed by the need to have a salt that crystallises easily. Unfortunately the chlorides of magnesium and zinc are not easy to crystallise, while magnesium sulfate is so soluble that it takes longer to evaporate sufficiently.

   30 cze 2023 · Metallic zinc reacts with weak acids very slowly. Sulfur has a strong affinity for zinc. When heated, the two powders react explosively to form zinc sulfide. Zinc sulfide is used to make television screens and fluorescent light bulbs. Zinc also reacts with halogens.
