fluids? ( 1 marks )
Ans.
0.9Percent W/V Nacl solution
5Percent W/V Dextrose solution
0.9Percent W/V Nacl solution &
5Percent W/V Dextrose solution
2Percent NaOH solution​

Answer 1

Answer:

0.9percent W/V Back solution.

Answer 2

Answer:

0.9% w/v NaCl solution is isotonic with body fluids.

Explanation:

• 0.9% w/v NaCl solution is isotonic with body fluids.
• 5% w/v dextrose solution is isotonic only initially, it changes into hypotonic as the dextrose metabolizes.
• The blood cells are isotonic with 0.9% NaCl solution.
• The cells when placed in this solution are in osmotic equilibrium across the cell membrane.
• No net movement of water is observed, when placed in 0.9% NaCl solution, thus it is isotonic with the body fluids.
• The isotonic solution does not show any movement of the water when a cell is placed in it.
