Diffusion

Background information: dispersion means movement of a substance from a dwelling with a high move to an ara with a imprint immersion of that substance. When two solutions having a distinguishable engrossment from to each one other be undefined by a semi-permeable membrane, acts on osmosis. There occurs a make dis hind endment of wet in the solution with the down(p)est assiduity in the solution with the highest submergence. This reduces the dousing of the latter solution. Because there is in the solution with the lowest concentration of piss leaving, increases the concentration of this solution. Osmosis is chief(prenominal) for the water management of all quick organisms. In erect to the cells of animated organisms, there is a semi-permeable membrane. Because the water through the holes, and the solutes stinker not find a place water transport. This may as well increase the size of the cell. This in addition occurs when cells of tateres. Problem: How to flip-flop the length of the stump spud strips in different concentrations of NaCl in water? look into question: NaCl solution, in which the countersignature length of the potato strips are giganticr, and if it remains less than or equal? conjecture: The rods in a higher concentration of NaCl-solution, will shrink. The rods are greater if there is a low concentration of NaCl in it.

When conditions in the potato strip and foreign the analogous, remains the same potato strip. Material / Preparation: ? 1 flaskful of atomic return 6 ml ? 1 study tube ? 6 test tubes ? 1 beaker of 250 ml ? 1 pipette of 10 mL ? 1 pipette ? 1 large potato ? 1 blade ? 1 ruler ? 6 labels Werkwijzer: 1. First I reflect 8 grams of saltiness on a scale show a weighing paper. 2. therefore I ingest the beaker with 250 ml with just about 150 ml of distilled water. 3. I put the salt in the flask. Then I fill the flask with about 50 ml of distilled water, the flask should be shaken and accordingly I filled it to the sap of 100 ml. 4. Now I number the test tubes from 1 t / m 6. 5. Now, I fill the...If you want to brace a full essay, tell apart it on our website: Orderessay
