An Intiative by Sri Chaitanya

When $A g C l$ react with $C l F_{3}$ chlorine gas is liberated along with the formation of $A g F_{2}$

Addition of excess chlorine water to $K I$ solution, first gives brown solution which becomes colourless

$P H_{4} I$ is the most stable of $P H_{4} X$ halides with respect to decomposition to $P H_{3}$ and $H X$

$C l O_{2}$ is the major bleaching agent in the pulp industry.

Detailed Solution

A) $C l F_{3}$ is a strong oxidizing agent and also good fluorinating agent. So it fluorinates the $A g^{+}$ ion and oxidize $C l^{-}$ ions when treated with $A g C l$

B) Chlorine water oxidized $K I_{2}$ brown $I_{2}$ solution and then oxidizes to colourless $H I O_{3}$
C) $P H_{3}$ is a weak base, so the stability of its salt increases with increase in the acidic character of HX. Further the H–X bond strength decreases from HF to HX
D) $C l O_{2}$ is prepared from $N a C l O_{3}$ . So use of $C l O_{2}$ increase the cost.
