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 12

A solution contains both FeSO₄ and CuSO₄. If a zinc strip is placed in the solution, which metal(s) will be displaced?

A strip of magnesium is placed in a solution of copper(II) sulfate. What will you observe?

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

A student adds a piece of iron to a solution of copper(II) sulfate and observes a color change. What is the color change and what does it indicate?

Calculate the mass of copper deposited when 6.5 g of zinc reacts completely with excess copper(II) sulfate solution. (Zn = 65, Cu = 63.5)

Describe the difference between single displacement and double displacement reactions.

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

Describe what happens when chlorine gas is bubbled through a solution of potassium iodide.

Explain why chlorine can displace bromine from potassium bromide solution, but iodine cannot.

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

Explain why displacement reactions are redox reactions.

Explain why potassium reacts more vigorously with water than sodium.

Explain why silver does not react with dilute hydrochloric acid, but zinc does.

State one industrial application of displacement reactions.

State the general form of a single displacement reaction.

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

Write the balanced chemical equation for the reaction between zinc and hydrochloric acid.

Write the ionic equation for the reaction between magnesium and copper(II) sulfate.

A solution contains 0.5 mol of CuSO₄. If 0.3 mol of magnesium is added and reacts completely, calculate the number of moles of copper metal formed.

A strip of chromium is placed in a solution of nickel(II) sulfate. Predict whether a displacement reaction will occur. Justify your answer using the reactivity series.
