Solution

The correct option is C Assertion is correct but Reason is incorrect
$C h r o m y l$ $c h l o r i d e$ test is used to determine the presence of $c h l o r i d e$ ions in a salt. It involves heating a sample suspected of containing $c h l o r i d e$ with $p o t a s s i u m$ $d i c h r o m a t e$ $(K_{2} C r_{2} O_{7})$ and $c o n c$ $s u l f u r i c$ $a c i d (H_{2} S O_{4}) .$
If $c h l o r i d e$ is present, $c h r o m y l$ $c h l o r i d e$ is formed and red flames seen. $(C r O_{2} C l_{2} : c h r o m y l$ $c h l o r i d e) .$
