Chemistry · NEET · NTA Exams — d- and f- Block Elements
STATEMENT-1 (Assertion): CO2 containing H2O changes yellow \(\mathrm{CrO}_{4}^{2-}\) into \(\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-}\).
STATEMENT-2 (Reason): Aqueous CO2 is acidic \(\left[\mathrm{H}_{2} \mathrm{CO}_{3}^{2-} \rightleftharpoons \mathrm{H}^{+}+\mathrm{HCO}_{3}^{-}\right]\) which converts \(\mathrm{CrO}_{4}^{2-}\) into \(\mathrm{Cr}_{2} \mathrm{O}_{7}^{2-}\).
In the light of the above statements, choose the correct answer from the options given below:
- Both Assertion and Reason are correct and Reason is a correct explanation for the Assertion.
- Both Assertion and Reason are correct but Reason is not a correct explanation for the Assertion.
- Assertion is correct but Reason is incorrect.
