-
What do we use to cut the potato?Cork borer
-
Why do we cut potato at all the same length?So they have the same surface area
-
What should be the same about all of the solutions we are testing?They should be the same volume
-
What is referred to as the solute and solvent in the experiment?The solute is the sucrose and the solvent is the water
-
What must you do before measuring the end mass?Dab off any excess water of the potato
-
What is a control variable of this experiment?Amount of time left in solution, volume of solution, surface area of potato
-
Which potato do we expect to increase and decrease in mass the most?The one with lowest sucrose conc will increase and the one with highest sucrose conc will decrease the most
-
What do we use to make sure the pieces of potato have the same surface area?A ruler and a sharp knife
-
What should be different about the solutions?They should have a ranging sucrose concentration
-
How do we carry out the experiment?Cut out pieces of potato, cut into equal cylinders, measure same volume of each solution into separate test tubes, measure start mass of potato, add to solutions, leave for 20 minutes, take out potatoes and dry off excess water, reweigh
-
What can we work out from our experiment?The percentage change in mass
