Question

Compared to 1 M sucrose solution, the ${\psi }_w$ of 1 M sodium chloride solution is

• A. High
• B. Same
• C. Lower
• D. None of the above

Answer 1

The correct option is A High

Water potential- it is the tendency of water to move from one area to another area[low to high]. Because $NaCl$ produces ions but sucrose doesn't produce ions. So $NaCl$ ions increases its DPD. Thus 1 M sodium chloride solution is higher than 1 M sucrose solution.

So the correct answer is 'High'.
