WebTo investigate the reactions between dilute hydrochloric and sulfuric acids with the metals magnesium, iron and zinc Diagram: Investigating the reactions of dilute acids with metals Method: Wear some safety glasses before handling acids Using a small measuring cylinder, add 5 cm 3 of dilute hydrochloric acid to each of three test tubes Websulfuric acid into a 100cm conical flask. 3. Warm the acid to about 60°C and, while stirring the acid, add magnesium oxidea little at a time. Make sure each portion dissolves … WebUndiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids is highly exothermic (releasing heat). The H2 gas that is produced as a result of the reaction might get ignited by the heat, and burn violently. john eckberg obituary
