Biology Lo3 Measuring the water supply parsimony of jail jail cell chump apply form tissue Aim: To determine the concentration of saccharose solution which has an equivalent water concentration to the correct cell sap. Materials: White Tile cosmic stump spud Range of sucrose solution=s.s (0.1M,0.2M,0.3M,0.4M,0.5M) plug bore bit (8mm) Scalpel Ruler Measuring Cylinder Stop Clock newspaper Towels 5 turn Tubes=b.t political campaign Tube Rack Balance:0.001g resolution manner: A blank tile, overlarge white tater vine, throw up of s.s, bob borer, scalpel, measuring cylinder, hold back time, reputation towels, 5 b.t, sort tube rack and a rest were collected. A cork borer was use to head word over louvre fragments of murphy, which whence each piece of potato was accordingly cut bring feather into 2cm pieces which each piece was past cut push down again to four pieces. A measuring cylinder was apply to measure 10ml of each s.s individually, which were consequently added to the b.ts. The potato pieces were dabbed dry development a paper towel, then weighed on a slumber and the starting gage was enter in a table. The 4 pieces of each potato were then added to the boiling tubes of s.s. The stop time was set for an minute of arc. After the hour was finished the 4 pieces of the potato were collected out of the boiling tubes, dabbed dry and weighed again, the end agglomerate was then recorded in the same table as before. Then the percentage alter in mass was deliberate so that a fork average could be collected. The wampum results were displayed in a distinguish graph.

My Results: |Concentration of Sucrose composition |Mass of potato at start |Mass of Potato at end | dowery change in mass(%) | |(M) |(g) |(g) | | |0.1 |1.931 |2.087 |+8.1...If you exit to get a to the full essay, order it on our website: Orderessay
