Introduction to Metal Reactions Explain how metals can react with solutions to form new compounds, often involving oxidation-reduction reactions . Briefly mention the types of solutions (acidic, basic, ionic) that metals typically react with. Picture suggestion : A general image of a metal immersed in a solution, showing a reaction in progress (e.g., bubbling or color change). Reaction with Acidic Solutions (e.g., Hydrochloric Acid) When metals like zinc (Zn) or magnesium (Mg) react with acids, they produce hydrogen gas and a metal salt . For example, zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas. Example reaction : Zn + 2 HCl → ZnCl 2 + H 2 (gas) \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 \text{(gas)} Zn + 2 HCl → ZnCl 2 + H 2 (gas) Picture suggestion : A metal reacting with an ac...
