Question

Sodium chloride, when heated with conc. $H_{2}S{O}_4$ and solid potassium dichromate gives :

• A. chromic chloride
• B. chromyl chloride
• C. chromous chloride
• D. None of these

Answer 1

Answer: (B)

chromyl chloride

Sodium chloride, when heated with conc. $H_{2}S{O}_4$ and solid potassium dichromate gives chromyl chloride.
$K_{2}C{r}_2{O}_7+NaCl\stackrel{H_{2}S{O}_4}{\to }Cr{O}_{2}C{l}_2+KCl+H_{2}O+N{a}_{2}S{O}_4$

Option B is correct.
