To determine the products formed when solution B reacts with the given mixtures, we need to understand the reactions involved and the properties of the compounds.
1. Reaction with phenylamine/nitrous acid mixture:
Phenylamine (also known as aniline) reacts with nitrous acid (HNO2) to form a diazonium salt. In the presence of a basic solution, such as sodium hydroxide (NaOH) from Solution B, the diazonium salt undergoes a reaction called diazotization. Diazonium salts are unstable and can decompose to form a variety of products, often accompanied by a change in color.
The reaction of phenylamine with nitrous acid forms a diazonium salt, which can then decompose to produce a red colored solution.
2. Reaction with butylamine/nitrous acid mixture:
Butylamine reacts with nitrous acid to form a corresponding diazonium salt. Similar to the reaction with phenylamine, this diazonium salt can also undergo decomposition in the presence of a basic solution.
The reaction of butylamine with nitrous acid forms a diazonium salt, which can then decompose to produce a dusty green colored solution.
3. Reaction with ammonia/nitrous acid:
Ammonia reacts differently with nitrous acid compared to amines. When ammonia reacts with nitrous acid, it forms a compound called ammonium nitrite (NH4NO2). The resulting solution of ammonium nitrite is pale yellow in color.
To summarize:
- Solution B, which is made by dissolving haphthalen-2-ol in sodium hydroxide, will react differently with each of the given mixtures.
- When Solution B reacts with the phenylamine/nitrous acid mixture, it will form a red colored solution.
- When Solution B reacts with the butylamine/nitrous acid mixture, it will form a dusty green colored solution.
- When Solution B reacts with the ammonia/nitrous acid mixture, it will form a pale yellow colored solution.
