Question

$H_{2} S$ gas is passed into aqueous solution of copper(II) chloride.
$C u C l_{2} (a q) + H_{2} S \to CuS +$ some other product
If CuS is precipitated then enter 1, else enter 0.

Open in App

Solution

When $H_{2} S$ is passed into aqueous solution of copper(II) chloride, $C u S$ is precipitated.
$C u C l_{2} + H_{2} S \to C u S + 2 H C l$
