Reactivity Series And Displacement Reactions Flashcards
What is the reactivity series?
The series obtained by arranging metals in the decreasing order of their reactivity
This series helps predict how metals will react with each other and with various substances.
What are displacement reactions?
Chemical reactions in which metals having high reactivity displace metals having less reactivity from their salt solutions
These reactions demonstrate the relative reactivity of metals.
What happens to metals with higher reactivity in displacement reactions?
They get oxidised
Oxidation involves the loss of electrons.
What happens to metals with lesser reactivity in displacement reactions?
They get reduced
Reduction involves the gain of electrons.
What are redox reactions?
Reactions in which reduction and oxidation take place simultaneously
The term ‘redox’ is a combination of ‘reduction’ and ‘oxidation’.
What observation occurs when a rod is dipped in CuSO₄ solution?
The blue color of the CuSO₄ solution fades slowly
This indicates the displacement of Cu²⁺ ions by a more reactive metal.
Write the equation for the reaction between Zn and CuSO₄.
Zn + CuSO₄ → ZnSO₄ + Cu
This reaction shows zinc displacing copper from its sulfate solution.
What is the equation of oxidation for Zn in the displacement reaction?
Zn → Zn²⁺ + 2e⁻
This indicates the loss of electrons by zinc.
What is the equation of reduction for Cu in the displacement reaction?
Cu²⁺ + 2e⁻ → Cu
This indicates the gain of electrons by copper ions.
What happens when a copper plate is immersed in AgNO₃ solution?
A layer of Ag is deposited on the copper plate
This indicates that copper displaces Ag ions from the solution.
