- C. Copper is reduced, and electrons move from copper to zinc.
- D. Zinc is oxidised, and electrons move from zinc to copper.
Example 3 · difficulty 2/5
Which function is performed by the salt bridge in an operating galvanic cell?
- A. It permits ionic migration that limits charge accumulation in the half-cells.
- B. It carries electrons internally from the anode compartment to the cathode compartment.
- C. It supplies metal atoms for oxidation at the anode.
- D. It forces both electrode potentials to become equal while current flows.
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2026 Chemistry Electrochemistry PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2026 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
