Chloropicrin is manufactured by the reaction between $Cl_2$,$NaOH$ and

$CH_3NH_2 + CHCl_3 + 3KOH \rightarrow X + Y + 3H_2O$;
Compounds $X$ and $Y$ are:

$C_6H_5NH_2 \xrightarrow{H_2SO_4, 180^{\circ}C} H_2NC_6H_4(SO_3H)$ (para). Which statement is correct for the product?

Assertion: Only a small amount of $HCl$ is required in the reduction of nitro compounds with iron scrap.
Reason: $FeCl_2$ formed gets hydrolysed to release $HCl$ during the reaction.
