The equilibrium  is shifted to the right in:

Canvas Classes · Accepted Answer

Step 1 — Understand the equilibrium:
Dichromate (, orange) and chromate (, yellow) are interconverted depending on pH.

Step 2 — Effect of pH:
The conversion involves  ions:

- In acidic medium (high ): Equilibrium shifts left (toward dichromate)
- In basic medium (low , high ):  neutralizes  equilibrium shifts right (toward chromate) ✓

Answer: Option (2) — Basic medium
