To solve the question regarding the blue color formation from the sodium fusion extract obtained from aniline when treated with iron (II) sulfate and sulfuric acid in the presence of air, we will follow these steps: ### Step-by-Step Solution: 1. **Understanding Sodium Fusion Extract**: - Sodium fusion extract is obtained by fusing an organic compound (in this case, aniline) with sodium metal. This process helps in detecting elements like nitrogen and halogens in the organic compound. 2. **Composition of Aniline**: ...

Redox reactions play a pivotal role in chemistry and biology. The values standard redox potential (E^(c-)) of two half cell reactions decided which way the reaction is expected to preceed. A simple example is a Daniell cell in which zinc goes into solution and copper sets deposited. Given below are a set of half cell reactions ( acidic medium ) along with their E^(c-)(V with respect to normal hydrogen electrode ) values. Using this data, obtain correct explanations for Question.
