Osmosis Practical

Reorder the following

• Dry the potatoes pieces to remove excess water

• Measure the starting mass of the potatoes

• Place the potato pieces into different concentration solutions

• Cut potatoes to the same size

• Leave for a few hours

Match the following

• Remove excess water

• Dry the potato pieces

• Make sure the same temperature

• Dependent Variable

• Concentration of solution

• Use a water bath

• Change in mass

• Independent Variable

• Allow osmosis to reach equilibrium

• Leave overnight

Match the following

• Gain water

• Potato in isotonic solution

• Lose water

• Potato in dilute solution

• Stays the same

• Potato in concentrated solution

Match the following

• Increase in mass and length

• Water moves out

• Decrease in mass and length

• Water moves in

• No change in mass and lenght

• Water moves in and out

Osmosis is the movement of ​ (a)   , from a ​ (b)   solution to a more ​ (c)   solution.
