Question

Solution of $\left(X\right)$ in $dil.HCl+H_{2}O\to Whiteturbidity\left(X\right)\stackrel{H_{2}S/HCl}{\to }Brownppt.\left(Y\right)$
$\left(X\right)$ is

• A. $B{i}^{3+}$
• B. $P{b}^{2+}$
• C. $C{d}^{2+}$
• D. $C{u}^{2+}$

Answer 1

Answer: (A)

$B{i}^{3+}$

Option (A) is correct.
$\left(X\right)$ is $B{i}^{3+}$.
$B{i}^{3+}$ + $dil.HCl+H_{2}O\to BiOCl\left(Whiteturbidity\right)$
$B{i}^{3+}$ $\stackrel{H_{2}S/HCl}{\to }B{i}_2{S}_3\left(Brownppt\right)$
