A solution contains both AgNO3 and CuSO4. If a piece of zinc is added, which metals will be displaced?
A strip of copper is placed in a solution of iron(II) sulfate. What will you observe?
A student adds a strip of zinc to a solution of magnesium sulfate. Will a reaction occur?
A student observes that when a piece of magnesium is added to copper(II) sulfate solution, a red-brown solid forms. Identify the solid and explain the observation.
Arrange the following metals in order of decreasing reactivity based on their ability to displace others from salt solutions: Iron, Zinc, Copper, Magnesium.
Describe what happens when a piece of sodium is added to water. Is this a displacement reaction?
Describe what happens when chlorine is passed through a solution of potassium iodide.
Explain why displacement reactions are important in the extraction of metals.
Explain why gold does not take part in displacement reactions with other metal salts.
Explain why magnesium can displace zinc from zinc sulfate solution but not sodium from sodium chloride solution.
If 2.0 g of zinc is added to excess copper(II) sulfate solution, how many grams of copper will be deposited? (Zn = 65, Cu = 63.5)
If a piece of iron is placed in a solution of copper(II) sulfate, what will be the color change observed?
In the reaction: Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s), which element is displaced?
State the general rule for predicting whether a displacement reaction will occur between two elements.
A solution contains both FeSO4 and Pb(NO3)2. If a strip of magnesium is added to the solution, which metal(s) will be displaced? Justify your answer based on the reactivity series.
A student adds a strip of lead to a solution of silver nitrate. Write the balanced chemical equation for the reaction and identify the type of reaction.
Aqueous solutions of potassium bromide and iodine are mixed. Predict whether a displacement reaction will occur and explain your reasoning.
Calculate the mass of iron that will be deposited when 5.6 g of aluminium reacts completely with excess iron(III) oxide according to the reaction: 2Al + Fe2O3 → 2Fe + Al2O3. (Al = 27, Fe = 56)
Consider the following reaction: 2Al(s) + 3CuCl2(aq) → 2AlCl3(aq) + 3Cu(s). Explain why this reaction occurs and what it indicates about the relative reactivity of aluminium and copper.
Explain, with reference to electron transfer, why displacement reactions involving metals are also considered redox reactions.
