straightforward to mix different concentrations successfully. The varying concentrations were worked out using a molarity table.
             The dependant variables of this experiment are the changes in length and mass of the potato cores, which should occur as a result of changing the independent variable. The length and mass of the cores were chosen as dependant variables as changes can be visible using standard laboratory equipment such as a top pan balance and a ruler.
             Pure water has the highest water potential, which is zero. If
