K2Cr2O7+2H2SO4 xrightarrowCold 2CrO3+2KHSO4+H2O CrO3 also called chromic acid. It is highly acidic and oxidizing agent.

Q. What will be the product when $K_{2} C r_{2} O_{7}$ reacts with cone. $H_{2} S O_{4},$ i.e. $K_{2} C r_{2} O_{7} + 2 H_{2} S O_{4} C o l d$

$C r_{2} O_{3}$

$C r O_{3}$

$C r_{2} (S O_{4})_{3}$

Both (a) and (b)

$K_{2} C r_{2} O_{7} + 2 H_{2} S O_{4} C o l d$ $2 C r O_{3} + 2 KH S O_{4} + H_{2} O$ $C r O_{3}$ also called chromic acid. It is highly acidic and oxidizing agent.
