Reactivity Series MCQ Quiz - Objective Question with Answer for Reactivity Series - Download Free PDF

The correct answer is Zinc.Key Points

• Zinc is more reactive than copper.
• Zinc is more reactive than copper metal and so it can displace copper from copper sulphate solution.
• Zinc displaces the metals present below it in the series.

Additional Information

• Reactivity of an element decreases from top to bottom in the given reactivity series.
  • Potassium (K) 
  • Sodium (Na) 
  • Calcium (Ca)
  • Magnesium (Mg) 
  • Aluminium (Al) 
  • Zinc (Zn) 
  • Carbon (C) 
  • Iron (Fe) 
  • Lead (Pb) 
  • Hydrogen (H) 
  • Copper (Cu) 
  • Silver (Ag)
  • Gold (Au)
• Platinum is known as a noble metal due to its remarkable resistance to corrosion and oxidation. It is one of the least reactive metals, which means that it does not easily react with other elements or compounds under normal conditions. This property makes platinum highly valuable for use in a variety of applications, such as in electronics, jewelry, and catalytic converters in vehicles.

The correct answer is Option 4.

Key Points

• Reactivity Series: Zinc is more reactive than copper, and lead is also more reactive than copper. This follows the order of reactivity in the metal reactivity series.
• Zinc Reactivity: Zinc can displace copper from its compounds due to its higher reactivity.
• Lead Reactivity: Lead, although less reactive than zinc, is still more reactive than copper.
• Iron and Copper Sulphate Reaction: An iron nail dipped in copper sulphate solution will turn brownish-red due to the deposition of copper, not yellow.

Additional Information

• Metal Reactivity Series: This series ranks metals from highest to lowest reactivity. Elements like potassium and sodium are at the top, while gold and platinum are at the bottom.
• Displacement Reactions: More reactive metals can displace less reactive metals from their compounds in aqueous solutions.
• Copper Sulphate Solution: It is a blue solution commonly used in school experiments to demonstrate displacement reactions.
• Iron and Copper Reaction: When iron reacts with copper sulphate, iron displaces copper, forming iron sulphate and copper metal, which deposits on the iron surface.
• Color Changes in Reactions: The color change in chemical reactions involving transition metals can often indicate the formation of different compounds or the deposition of metals.

The correct answer is Magnesium.

Key Points

• Magnesium is higher in the reactivity series compared to Iron, Aluminium, and Zinc.
• When magnesium reacts with sulphuric acid, it displaces hydrogen gas rapidly due to its high reactivity.
• The reactivity series of metals places magnesium above zinc, iron, and aluminium, making it more reactive.
• Hydrogen gas bubbles will form at a faster rate when magnesium is used in the reaction with sulphuric acid.

Additional Information

• Reactivity Series: The reactivity series is a list of metals arranged in order of decreasing reactivity to displace hydrogen from acids and water.
• Hydrogen Displacement: Metals higher in the reactivity series can displace hydrogen gas from acids faster than those lower in the series.
• Magnesium (Mg): A lightweight, silvery metal that reacts vigorously with acids to produce hydrogen gas.
• Sulphuric Acid (H₂SO₄): A strong acid commonly used in chemical reactions to test the reactivity of metals.
• Safety Precautions: When performing reactions with acids, appropriate safety measures like wearing gloves and goggles should be taken to prevent harm.
