The effect of sugar concentration on the mass of potatoes AIM This investigation is based upon osmosis. Hence, I am carrying out this experiment to investigate how different concentrations of sucrose (the independent variable) and distilled water solution affect the mass of a potato tuber. APPARATUS 6 BOILING TUBES KNIFE TEST TUBE STAND SUCROSE (CONCENTARION OF 0.5 M)- AMOUNTS (IN ml): 25, 20, 15, 10, and 5. CORK AND BORER DISTILLED WATER-SAME AMOUNTS AS ELECTRIC SCALES SUCROSE SOLUTION POTATO MEASURING CYLINDER BACKGROUND INFORMATION This experiment is based upon osmosis and therefore a clear understanding of this is to be obtained. Osmosis can be summed up as, 'the movement of water molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.' Osmosis also depends upon water and solute potential. ?-this is the Greek letter 'psi' for water potential. Pure, distilled water has a water potential of zero. Therefore, solutions containing...
