Displacement Reactions

Chemistry ⇒ Chemical Reactions and Equations

Displacement Reactions starts at 9 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Displacement Reactions. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 11

A solution contains both AgNO₃ and CuSO₄. If a piece of copper is added, which metal will be deposited first?

A solution contains both FeSO₄ and CuSO₄. If a zinc strip is added, which metals will be displaced?

A strip of zinc is placed in a solution of copper(II) sulfate. After some time, the blue color of the solution fades and a reddish-brown deposit forms. Explain the changes observed.

A student adds a piece of magnesium to a solution of lead(II) nitrate. Predict the products and write the balanced equation.

A student adds a strip of copper metal to a solution of silver nitrate. What will be observed?

Arrange the following metals in order of decreasing reactivity based on their ability to displace each other from solutions: Copper, Zinc, Iron, Silver.

Describe the difference between single displacement and double displacement reactions.

Describe the role of the reactivity series in predicting the outcome of displacement reactions.

Explain why displacement reactions are important in the extraction of metals.

Explain why magnesium can displace zinc from zinc sulfate solution, but copper cannot.

Explain why no reaction occurs when a copper rod is placed in a solution of zinc sulfate.

Write the balanced chemical equation for the reaction between bromine and potassium iodide solution.

Write the balanced chemical equation for the reaction between chlorine gas and potassium bromide solution.

Write the balanced chemical equation for the reaction between iron and copper(II) sulfate.

A solution contains both FeSO₄ and Pb(NO₃)₂. If a strip of zinc is added, which metals will be deposited? Write the balanced equations for the reactions.

A student adds a piece of magnesium ribbon to a solution containing both copper(II) sulfate and silver nitrate. Which metal(s) will be displaced from solution? Justify your answer based on the reactivity series.

A student observes that when a certain metal X is added to a solution of metal Y sulfate, no reaction occurs. However, when metal Y is added to a solution of metal X sulfate, a reaction occurs. What can you conclude about the relative reactivity of X and Y?

Explain, with reference to the reactivity series, why gold does not undergo displacement reactions with any metal salt solution.

Given the following reactivity series: K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Ag > Au, predict whether a reaction will occur when a strip of iron is placed in a solution of lead(II) nitrate. Write the balanced chemical equation if a reaction occurs.
