Experiment with Diffusion Essay

IntroductionThe hunting expedition of molecules from an scene of action of greater ducking to an area of less concentration is called Diffusion. Osmosis is the diffusion of pissing system through and through a selectively pervious membrane from an area with greater concentration of weewee to an area with less concentration. A Hypertonic Solution is a final result of a higher concentration of solutes and a smaller concentration of water molecules than some other(prenominal) resolvent. However, an Isotonic Solution is a dissolvent that contains an equal concentration of solutes and of water molecules, the like as another solution. A solution that contains a lower concentration of solutes and a higher concentration of water molecules than another solution is called a Hypotonic Solution. A cell that has a Selectively leaky Membrane has a plasma membrane that allows certain substances to pass through to a greater extent readily than others.From this I have stimulate up with a hypothesis of what leave behind happen with the 2 suitcases. The one containing pertly water and regularize into saltiness water leave alone lose charge, based on a Hypertonic Solution give tongue to above. However, the bag containing salt water and put in smart water will gain weight based on the Hypotonic Solution also stated above.Procedure1.First we folded one side of the membrane-like bag we were given and tied it shut oer the folded part.2.Then we alter it 2/3 right of fresh water and tied the other rarity shut, and weighed it.3.Next we weighed it and put the bag into the saltwater.4. by and by that, we did Steps 1, 2, and 3, except, we filled the bag 2/3 full-of-the-moon with saltwater, weighed it, and put it into fresh water.5.After about 30 minutes we went back and took both bags out and weighed them.Results beforehand we placed the bags in the salt and fresh water we weighed them. The bag filled with freshwater weighed 18.3 grams and the bag containing t he saltwater weighed about 23.9 grams. After they had soaked in their rightful water for about half an hour we weighed them again. The freshwater weighed 16.2 grams and had sustained an 8.9% decrease of weight. The saltwater weighed 25.1 grams and had reach a 9.5% increase of weight.ConclusionWell, the freshwater bag lost weight through the Hypertonic Solution theorem. Because there was no salt in it, the fresh water left the cell to mix with the salt outside its cell. No salt molecules could take up in, in return. The saltwater bag had gained weight during the 30 minute time period. It had make this through the Hypotonic Solution theorem. The freshwater outside the bag(cell) had entered it because there werent many a(prenominal) water molecules inside the cell. Causing the bag filled with saltwater to gain weight.
