When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.
The zinc granules will appear shiny and metallic before the reaction with dilute HCl. After the reaction, the zinc granules will dissolve, producing colorless zinc chloride solution and releasing hydrogen gas.
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
Zinc liberates hydrogen gas when treated with dilute HNO3.
coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.

When dilute sulfuric acid is added to zinc granules, a displacement reaction takes place, resulting in the formation of zinc sulfate and hydrogen gas. This reaction is exothermic, which means it releases heat energy.
When zinc granules are added to dilute sulfuric acid, a chemical reaction occurs where the zinc reacts with the sulfuric acid to produce zinc sulfate and hydrogen gas. This reaction also generates heat, so the mixture may get warm. Additionally, bubbles of hydrogen gas can be seen as they are released from the solution.
The color change of zinc granules when reacting with HCl is not significant. However, over time, the zinc granules will start to lose their shine and develop a dull appearance due to the formation of zinc chloride and hydrogen gas.
They get converted to zinc sulfate
When zinc granules react with hydrochloric acid, the zinc dissolves to form zinc chloride and releases hydrogen gas. The color change is not significant, and the zinc itself does not change in color during this reaction.
To make zinc nitrate, you would typically react nitric acid with zinc oxide or zinc metal. Nitric acid is the acid needed for the reaction, while zinc oxide or zinc metal can serve as the base to neutralize the acid and form zinc nitrate.
The coating formed on the zinc granules when zinc reacts with ferrous sulfate is black in color. It is due to the formation of ferrous sulfide as a result of the reaction.
