Objective: The question ask to put zinc granules in the beaker containing acid either hydrochloric acid or sulphuric acid and ask for what we observe.
Observation: Air Bubbles comes out from the granules, and Conical flask becomes warm.
Inference: Zinc granules react with hydrochloric acid or sulfuric acid and forms hydrogen gas.
Zn(s) + 2HCl(aq) → ZnCl2(aq)+ H2↑ + heat
Zn(s) + 2H2SO4(aq) → ZnSO4(aq) + 2H2↑ + heat
Caution: Acids are corrosive and harmful for skin. Avoid touching them with bare skin.
Next: Quick lime reaction with water.Activity 1.4.
