A solution of `Cr_(2)O_(s)` in amyl alcohol has a________ colour.

Options

A. Yellow
B. Blue
C. Green
D. Orange-Red

Answer

To determine the color of a solution of `CrO5` in amyl alcohol, we can follow these steps:

### Step 1: Identify the Compound
The compound in question is `CrO5`, which is chromium pentoxide. It is important to note that this compound is different from `Cr2O3` or other chromium oxides.

### Step 2: Understand the Solvent
Amyl alcohol, also known as pentanol, is an organic solvent. The interaction of `CrO5` with amyl alcohol will influence the color of the solution.

### Step 3: Recall the Color Characteristics
From chemical knowledge, `CrO5` is known to impart a specific color when dissolved in certain solvents. It is essential to remember the characteristic colors associated with different chromium compounds.

### Step 4: Conclude the Color
When `CrO5` is dissolved in amyl alcohol, it is known to produce a blue color. This is a well-documented property of chromium pentoxide in organic solvents.

### Final Answer
The solution of `CrO5` in amyl alcohol has a **blue** color.
