Osmosis 1. Introduction 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.Vinegar 2.procedure 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.3.Cover 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.3.Data and Drawings egg in vinegar mass of egg volume of egg volume of liquid Before 59.7 56 400 After 86.2 92 370 4.anylasis 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.5.conclusion 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 didn't let much liquid through.Corn Syrup 2.procedure 1. Fill clean beaker to 200ml. with corn syrup.2. After rinsing egg, place in beaker. Record how much syrup placed in beaker.3. Next day, remove the egg and record observations, mass, volume of egg and syrup.3.Data and Drawings egg in corn syrup mass of egg volume of egg volume of liquid Before 86.2 92 200 After 44.1 37 237 4.anylasis The egg has shrunk in the corn syrup because the water in the egg came out and the volume was lower and there was more water in the beaker than before. The egg looked like it was deflated and you could see the yolk. Instead of the egg being a hypertonic solution the corn syrup is and the egg is a hypotonic solution. The arrows show that the liquid is coming out instead of going through the eggs membrane. As...

Osmosis Investigation Essay

2093 words - 8 pages Osmosis Investigation Aim:The aim of this investigation is to explore osmosis in potato cells and find approximately the concentration of sucrose within potato cells by measuring the change in mass of potato chips when immersed in different sucrose solutions for a set period of time Introduction: Osmosis happens in the cells of all living things. It is a simple process where water molecules diffuse from one cell to

529 words - 2 pages Background Knowledge: Osmosis definition: Diffusion of water molecules through a semi permeable membrane from a higher concentration to a lower concentration until the concentration on both sides is equal. Osmosis in animal cells: The cell membrane is the partially permeable membrane in animal cells. If the cells were placed in distilled water they gain water, swell and burst. This is known as haemolysis. Osmosis in plant cells: The

In other words the water inside the potato is leaving it, as it is passing from a weak concentration to a strong concentration. Making it smaller and lighter. Where as with water as the solution, the potato piece stayed the same but theoretically it should have gained weight therefore became turgid. In the
