On adding zinc to copper sulphate solution:

🔑Key Points:
-When zinc is added to copper sulphate (CuSO4) solution due to more reactivity of zinc, copper is replaced by zinc and forms zinc sulphate.
-During the process, the colour of the solution changes from blue to colourless.
-The chemical equation of the reaction,
-Zn+CuSO4→ZnSO4+Cu

✏️Types of Chemical Reactions:
-Decomposition reaction: The opposite of a combination reaction, a complex molecule breaks down to make simpler ones. Such reactions are represented by equations of the following form: AB → A + B.
-Precipitation reaction: Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming. Such reactions are represented by equations of the following form: A + Soluble salt B  → Precipitate + soluble salt C.
-Neutralization reaction: An acid and a base react with each other. Generally, the product of this reaction is salt and water. Such reactions are represented by equations of the following form: Acid + Base → Salt + Water.
-Combustion reaction: Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat. Such reactions are represented by equations of the following form: A + O2 → H2O + CO2.
-Displacement reaction: One element takes place with another element in the compound. Such reactions are represented by equations of the following form: A + BC → AC + B.
