- B. 300 S cm² mol⁻¹
- C. 391 S cm² mol⁻¹
- D. 517 S cm² mol⁻¹
Example 3 · difficulty 4/5
The same quantity of electricity is passed through two electrolytic cells containing AgNO₃ and CuSO₄ solutions respectively (atomic masses: Ag = 108, Cu = 63.5). The ratio of the mass of silver deposited to the mass of copper deposited is:
- A. 3.4 : 1
- B. 1 : 3.4
- C. 108 : 63.5
- D. 1.7 : 1
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 2017 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 2017 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.
