Question

Complete the co-relation: \[ \text{CuI}_2 \text{: Brown} :: \text{AgCl} \text{: ............................} \]

• A. White
• B. Yellow
• C. Green
• D. Red

Hint:

In inorganic chemistry, the color of precipitates can be an important characteristic for identification. For example, \(\text{CuI}_2\) is brown, while \(\text{AgCl}\) is white.

Answer 1

The Correct Option is A

In this correlation, \(\text{CuI}_2\) is brown in color. Now, \(\text{AgCl}\) (Silver chloride) is a white precipitate. It is a well-known fact that \(\text{AgCl}\) appears white when formed as a precipitate in reactions involving silver ions. Therefore, the correct match for \(\text{AgCl}\) is "White."
