a. Conc H2SO4
b. Conc HCl
c. HNO3

Answer (1)

Granular zinc reacts effectively with Concentrated Hydrochloric Acid to produce hydrogen gas. In contrast, Concentrated Sulfuric Acid can cause side reactions, and Nitric Acid leads to the formation of nitrogen oxides instead of hydrogen. Therefore, concentrated hydrochloric acid is preferred for this chemical reaction. ;
