Statement 1: Correct statement as it gives oxy acid H2Cr2O7; 2CrO3 + H2O → H2Cr2O7. Statement 2: Correct statement: K2Cr2O7 + 2H2SO4 (concentrated and cold)→ CrO3- (bright orange) + 2KHSO4 + H2O

Q. Statement 1: $C r O_{3}$ is an acid anhydride
Statement 2: $C r O_{3}$ is obtained as bright orange crystals by the reaction of $K_{2} C r_{2} O_{7}$ with cold concentrated $H_{2} S O_{4}$

If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1.

If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1.

If Statement 1 is true but Statement 2 is false.

If Statement 1 is false but Statement 2 is true

Statement 1: Correct statement as it gives oxy acid $H_{2} C r_{2} O_{7}; 2 C r O_{3} + H_{2} O \to H_{2} C r_{2} O_{7} .$
Statement 2: Correct statement: $K_{2} C r_{2} O_{7} + 2 H_{2} S O_{4}$ (concentrated and cold) $\to C r O_{3}^{-}$ (bright orange) $+ 2 KH S O_{4} + H_{2} O$
