Question

write an activity to show Osmosis draw the required diagram

Answer 1

Osmiss is the spontaneous net movment of solventmolecules through a semi permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two side

Answer 2

To experiment with osmosis using potatoes, you will need two shallow dishes, a potato, knife, water and salt.

Fill both of the dishes with an inch of water. Add two tablespoons of salt to only one dish, while leaving the other plain. (Be sure to label which dish is plain and which has salt added to it.) Slice the potato lengthwise, so that you end up with several pieces that are flat on both sides. Place a few pieces of potato into the plain water, and an equal number of pieces into the salty water.

Allow the potatoes to sit for 20 minutes

The potatoes that were in the salt water now appear mushy because of osmosis. Due to the higher concentration of salt in the water surrounding the potatoes, the water moved from the potatoes and into the surrounding water to balance it out. This left the potatoes in the salt water mushy, while the ones in the plain water have no change to their appearance.
