WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things.

concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration is called hypertonic solution

My conclusion is that the higher salt concentration in the solution the greater the decrease in mass of the potato will be‚ the graph I have drawn supports my conclusion. The 10% salt concentration shows that on average the potato loses 2.6% of its overall mass. 20% salt concentration shows a further decrease in mass this time it is an average of 13% overall mass decrease. 30% salt concentration shows an average decrease of 18.8% in overall mass. The 0% salt concentration actually shows a mass increase
