Metals that are higher than H + ions on the Activity Series can be oxidized by the H + ions (i.e. When an acid reacts with metals, salt and hydrogen gas are produced. Most metals react with acids to produce a corresponding salt and hydrogen gas. Knowledge of reactions limited to those of magnesium, zinc and iron with hydrochloric and sulfuric acids. (e) Copper displaces zinc from a zinc sulfate solution. You can refer to NCERT Solutions for Class 10 Science Chapter 3 Metals and Non-metals to revise the concepts in the syllabus effectively and improve your chances of securing high marks in your board exams. Metals that are more active than acids can undergo a single diplacement reaction. With "real" acids, almost all metals will react. Hold a glowing splint at the opening of the test tube when you release the gas. a substance that turns one color in a … (d) Sodium is a very reactive metal.
