Group Information

  1. Length Of Pieces = 4cm
  2. No Of Pieces Per Test Tube = 1
  3. Solutions Used = All  (Distilled Water, 0.1 – 0.4M and 0.6M (solutions between 0.1 – 0.4 increased by 0.1 each time)
  4. Amount Of Solution = 10ml

Personal Information

P6 a I) In our experiment to study Osmosis I think that the 0.6 M solution will give the chip a rubbery effect because in the 0.6 M solution the salt will absorb all of the moisture out of the chip. The 0.4 M solution will have a large effect on the chip but not as large as the 0.6 M solution. I think that the 0.3 M solution will be balanced so the chip will stay as it is. The 0.2 M solution will make the chip bulkier because the chip will absorb the water out of the solution. The 0.1 M solution will have more effect than the 0.2 M solution but not as much as the effect that Distilled water will have on the chip because distilled water has no salt strength, this means that none of the cells will shrink however they will grow in size causing them to gain weight.

P6 a II) The varying factor will be the strength of the salt solutions used which are Distilled Water, 0.1 – 0.4M(solutions between 0.1 – 0.4 increased by 0.1 each time) and 0.6M.

P6 a III) The controlled factors will be the size of the potato and the amount of salt solution used.

P6 b I) We will aim to get two different sets of results.

P6 b II) The thing that we will measure will be the weight of the chip before and after the experiment.

A6 b I) The graphs conclude that as the solution got higher the weight gained ...
