Question

Four different experiments were conducted by students of Class X. Who among them was able to perform a displacement reaction?

1. 1. Navin took a beaker containing some aqueous solution of CuSO4, and added a piece of magnesium strip in it.
2. II. Ayush took a beaker containing some aqueous solution of CuSO4, and added some platinum pieces in it.
3. III. Sneha took a beaker containing some aqueous solution CuSO4, and added some copper tumings in it.
4. IV. Akriti took a beaker containing some aqueous solution CuSO4, and added a piece of silver wire in it.

• A. All
• B. i only
• C. ii only
• D. iv only

Answer 1

Answer:

B. i only

• Navin's experiment with magnesium resulted in a displacement reaction.

• A displacement reaction, also known as a single displacement reaction or single replacement reaction, is a type of chemical reaction where one atom or ion in a compound is replaced by another atom or ion of a different element.
