The correct answer is B. Reducing property.
In its reaction with silver nitrate, C2H2 reduces Ag+ to Ag. This is because C2H2 is a reducing agent, which means it can donate electrons to another substance. When C2H2 reacts with Ag+, the C2H2 molecule donates electrons to the Ag+ ion, causing the Ag+ ion to be reduced to Ag metal.
The other options are incorrect because they do not describe the properties of C2H2 in this reaction. Option A is incorrect because C2H2 is not an oxidizing agent. Option C is incorrect because C2H2 is not a base. Option D is incorrect because C2H2 is not an acid.
Here is a more detailed explanation of each option:
- Option A: Oxidising property. This is incorrect because C2H2 is not an oxidizing agent. An oxidizing agent is a substance that can accept electrons from another substance. In this reaction, C2H2 is donating electrons to Ag+, so it is not an oxidizing agent.
- Option B: Reducing property. This is the correct answer because C2H2 is a reducing agent. A reducing agent is a substance that can donate electrons to another substance. In this reaction, C2H2 is donating electrons to Ag+, so it is a reducing agent.
- Option C: Basic property. 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z"/> Subscribe on YouTube
