Potassium dichromate can be converted to potassitun chromate by adding
- A \(\mathrm{KOH}\)
- B con(c)\(\mathrm{H}_{2} \mathrm{SO}_{4}\)
- C \(\mathrm{NH}_{4} \mathrm{OH}\)
- D acetic acid
Answer & Solution
Correct Answer
(A) \(\mathrm{KOH}\)
Step-by-step Solution
Detailed explanation
Potassium dichromate \(\left(\mathrm{K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}\right)\) can be converted into potassium chromate \(\left(\mathrm{K}_{2} \mathrm{CrO}_{4}\right)\) by adding potassium hydroxide \((\mathrm{KOH})\).
