AI Generated Solution

To solve the question regarding the formation of the blue color in the Prussian blue precipitate obtained from the sodium fusion extract of aniline treated with iron (II) sulfate and sulfuric acid in the presence of air, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Sodium Fusion Extract**: - Sodium fusion extract is obtained by fusing a compound (in this case, aniline) with sodium. This process helps in detecting the presence of nitrogen and carbon in the compound. 2. **Formation of Sodium Cyanide**: ...

Redox reactions play a pivotal role in chemistry and biology. The values standard redox potential (E^(o)) 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.
