Question

Drag each label to the correct diagram.

In your school’s chemistry lab, you use a U-shaped apparatus with a semipermeable membrane at the bottom to test the osmotic pressure of two different substances dissolved in water. The substances you test are 1.0 molar ammonia (NH3) and 1.0 molar hydrochloric acid (HCl). As a control, you also test the osmotic pressure of pure water.
Which substance produced which result?

Answer 1

left = HCl

Middle = NH3

Right = water

Step-by-step explanation:

HCl is a strong acid so it will have the strongest effect

NH3 is a weak acid so it will have a small effect

Water has no effect
