Question

In 0.1 M solution of a non electrolyte, $\Psi$ w value will be:-

• A. zero bar
• B. +2.3 bar
• C. -2.3 bar
• D. -22.4 bar

Answer 1

The correct option is A zero bar

The water potential of pure water is zero. The water potential lowers when solute is added to pure water.The solute potential of a 0.1 M solution of

distilled water and sucrose at 20º C at standard atmospheric pressure is -0.23.

So the correct answer should be option C "-2.3 bar".
