17. Electrolytic reduction of sodium from NaCl
- Assertion (A): Sodium is obtained from the electrolytic reduction of both aqueous and molten NaCl.
- Reason (R): Na and chloride ions are present in both molten and aqueous form of NaCl.
Explanation:
- When NaCl is dissolved in water, it dissociates into Na+ and Cl- ions. These ions are then subjected to electrolysis, where Na+ ions are reduced to form sodium metal at the cathode.
- Similarly, in the molten state of NaCl, Na+ and Cl- ions are also present. When molten NaCl is subjected to electrolysis, sodium metal is obtained at the cathode.
Conclusion: Both in the aqueous and molten forms of NaCl, the presence of Na+ ions allows for the electrolytic reduction of sodium.

18. Osmotic pressure of dialysing fluid and blood
- Assertion (A): Dialysing fluid has the same osmotic pressure as blood.
Explanation:
- Dialysing fluid is designed to have a similar osmotic pressure to that of blood to prevent an osmotic gradient that could lead to the loss of essential solutes or fluid from the blood during the dialysis process.
- If the osmotic pressure of the dialysing fluid were significantly different from that of blood, it could result in complications such as fluid shifts or imbalances in electrolyte levels.
Importance of matching osmotic pressure:
- Matching the osmotic pressure of the dialysing fluid with that of blood ensures that the exchange of waste products and excess fluids across the dialysis membrane occurs at a controlled rate without causing harm to the patient.
- This balance helps in maintaining the patient's overall fluid and electrolyte balance during the dialysis treatment, promoting better outcomes and reducing the risk of complications.
Conclusion: It is crucial for the osmotic pressure of the dialysing fluid to be carefully regulated and matched to that of blood to ensure safe and effective dialysis treatment.
