The mineral (A) is $[CuCl_{2} . x Cu (OH)_{2}]$ . A 45.05 ml solution of 0.5089 M HCl was required to react completely with 1.6320 g of the compound $(A)$ whose molar mass is 427 . Hence, $x$ is

Options:

Answer:

Solution:

In CuCl₂ ⋅ xCu(OH)₂, OH⁻ is neutralized by HCl.

$\frac{1.632}{427} \times 2 x = \frac{45.05 \times 0.5089}{1000} ⟹ x = 3$
