What is the colour of zinc after when zinc granules react with hcl?
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.
Color of zinc granules after reaction with dilute hcl?
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.
What is the effect on zinc granules when added to dilute sulphuric acid?
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.
What is the colour of the copper sulfate solution when zinc granules are added to it?
The color of the copper sulfate solution changes from blue to colorless when zinc granules are added to it. This is because zinc displaces copper in the solution through a chemical reaction, forming zinc sulfate and leaving the solution without copper ions responsible for its blue color.
What happens zinc granules are placed in copper sulphate solution?
When zinc granules are placed in a copper sulfate solution, zinc will undergo a displacement reaction with copper, displacing copper ions in the solution. This reaction will result in the formation of zinc sulfate solution and solid copper. The blue color of the copper sulfate solution will fade as the reaction proceeds.
What is the colour of the coating formed on the zinc granules when zinc reacts with ferrous sulphate?
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.

The color of the copper sulfate solution changes from blue to colorless when zinc granules are added to it. This is because zinc displaces copper in the solution through a chemical reaction, forming zinc sulfate and leaving the solution without copper ions responsible for its blue color.
Is there a temperature change when zinc granules react with hydrochloric acid?
yes it heats up
What happens zinc granules are placed in copper sulphate solution?
When zinc granules are placed in a copper sulfate solution, zinc will undergo a displacement reaction with copper, displacing copper ions in the solution. This reaction will result in the formation of zinc sulfate solution and solid copper. The blue color of the copper sulfate solution will fade as the reaction proceeds.
Sulfuric acid is poured on zinc granules?
When sulfuric acid is poured on zinc granules, a chemical reaction occurs where zinc metal reacts with sulfuric acid to produce zinc sulfate and hydrogen gas. The reaction is exothermic, releasing heat energy. Zinc sulfate will be formed as a salt solution and hydrogen gas will evolve.
Is it chemical change when hydrochloric acid reacts with zinc?
Yes.
Can zinc color change into brass color?
YES
When zinc reacts with acids producing hydrogen gas is it a chemical or physical change?
When zinc reacts with acids to produce hydrogen gas, it is a chemical change because new substances are formed (zinc salts and hydrogen gas) with different properties from the original substances.
During reaction of zinc and sulfuric acid what happens to zinc granules?
They get converted to zinc sulfate
