We recently did an experiment on osmosis and it really helped me understand diffusion and osmosis much better This experiment was really easy We put the egg into three different types of liquids vinegar corn syrup and water My hypotheses for the egg in the vinegar was that the shell would be removed and dissolve For the corn syrup I thought that the whole egg would break apart including the including the yolk My hypothesis for the water was that nothing will happen to the egg 1 Get egg and weight it Find volume of egg using water displacement method in ml 2 Use graduated cylinder to measure 400ml of vinegar Place egg in beaker and pour vinegar next 3Cover beaker with handiwrap and use a rubber band to prevent evaporation Lets sit for two days 4 After two days observe what happened and write it down in the space labeled observations mass of egg volume of egg volume of liquid The vinegar has dissolved the shell of the egg and some vinegar has gone into the egg by osmosis The vinegar was a hypotonic solution and the egg was hypertonic solution There is some vinegar that has diffused through the membrane of the shell The volume is much more than before along with the mass The egg was really slimy it was a bit bigger and had no hard shell The arrows show that there is vinegar going into the egg and not leaving the egg In conclusion the vinegar has gone from an area with lesser concentration with an area with greater concentration The membrane of the egg in vinegar is impermeable This membrane is very tight and didnt let much liquid through1Fill clean beaker
