The electrolyte in ECM is an aqueous solution of
  • a)
    NaCl
  • b)
    KNO3
  • c)
    NaNO3
  • d)
    All of the above
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The electrolyte in ECM is an aqueous solution ofa)NaClb)KNO3c)NaNO3d)...
In ECM, both the tool electrode and the workpiece are submerged in an electrically conductive electrolyte, usually an aqueous salt solution such as sodium chloride (NaCl) or sodium nitrate (NaNO3). A constant potential is applied between the two electrodes ensuring the workpiece becomes the anode (positive electrode).

The electrolyte in ECM is an aqueous solution ofa)NaClb)KNO3c)NaNO3d)...
Explanation:

Electrolyte in ECM:
- The electrolyte in ECM refers to the Electrochemical Machining process, which involves the use of an aqueous solution as the electrolyte.

Aqueous Solution Composition:
- The aqueous solution used in ECM typically contains sodium nitrate (NaNO3).
- This compound is chosen for its ability to conduct electricity and facilitate the electrochemical reactions necessary for the machining process.

Options Analysis:
- Option 'A' (NaCl) is not the correct answer as sodium chloride is not commonly used in ECM due to its limited ability to act as an electrolyte.
- Option 'B' (KNO3) is also not the correct answer as potassium nitrate is not commonly used in ECM. Sodium nitrate is the more commonly used compound in this process.
- Option 'C' (NaNO3) is the correct answer as sodium nitrate is a common electrolyte used in ECM due to its effectiveness in facilitating the required electrochemical reactions.

Conclusion:
- In conclusion, the electrolyte in ECM is an aqueous solution containing sodium nitrate (NaNO3) as the key component to enable the electrochemical machining process.
