TestHub · Accepted Answer

The decomposition of NaNO₃ gives O₂ (A) and NaNO₂ (B).

$2 N a N O_{3} Δ 2 N a N O_{2} + O_{2}$

A (O₂) reacts with HCl in the presence of CuCl₂ to produce Cl₂ (C) and H₂O.

$4 H Cl + O_{2} C u C l_{2} 2 C l_{2} + 2 H_{2} O$

O₂ is colourless, and Cl₂ is greenish-yellow. Therefore, the colours of C and A are greenish-yellow and colourless, respectively.
