NEET 2017 Chemistry Electrochemistry Questions
Use this page to connect the official 2017 paper with current Chemistry practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
What to master
conductance, electrochemical cells, the Nernst equation and electrolysis.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5
Given Λ°m(CH₃COONa) = 91.0, Λ°m(HCl) = 426.0 and Λ°m(NaCl) = 126.0 S cm² mol⁻¹ at 298 K, the limiting molar conductivity of acetic acid is:
- A. 461 S cm² mol⁻¹
- 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.
