Find out what affect the change of concentration in the sucrose solution has on the mass of a potato chip.

Extracts from this document...

Introduction

Osmosis Investigation By Umar Khan Introduction In this experiment I will be taking five similar potato chips and putting them into different sucrose solutions (each one with a different concentration) and observing the effect that each concentration has on the size of the potato chip. Aim I am doing this investigation in an endeavour to find out what affect the change of concentration in the sucrose solution has on the mass of a potato chip. Background information > Osmosis is the movement of water molecules across a partially permeable membrane from an area with high concentration to an area with low concentration > The opposite of osmosis is active uptake, this is when water moves from an area with a low concentration to an area with low concentration. ...read more.

the water in the solution will move from the solution to the potato chip and as a result increasing the mass of the potato chip. I also predict that the concentration of the solution and the mass of the potato chip will be directly proportional to each other. Variables In this investigation I will change the concentration of the solution and I will be keeping the size of the potato and the temperature of the solution the same. Equipment Below is the apparatus that I will be using for my investigation. > Stop watch > Cutting tile > Small knife > Measuring cylinder > Distilled water > sucrose > Potatoes > Weighing scale > Potato cutter > Cling film > Ruler Method > Firstly I will cut five pieces of potato. ...read more.

Conclusion

rack for 15hours, after which I will measure the weights and lengths of each potato chip and then show my findings in a graph and table. Fair test To ensure that my investigation is conducted fairly I will be weighing each potato chip to ensure that all the chips are the same weight, I will also measure each potato chip to keep them the same size. Also I will be putting all my potatoes in the same place so that they are kept at the same temperature and receive the same amount of sunlight. Safety To ensure that my experiment is conducted safely I will wear goggles to protect my eyes from any possible hazards. I will also be using a small blunt knife so as that I do not injure myself. ...read more.

    faster and therefore more of a change could take place in the hotter temperatures. * The atmosphere, because of the humidity the osmosis could be affected in some way. The changeable variable in my experiment was the concentration of sucrose in the solution.

    This was because, if I had weighed the potatoes with the bowl, then I would have to take the weight of the bowl away from that result. Table of results In the table below, it shows the �solution� column, which are the 6 different types of solutions.

  1. Osmosis Chip Investigation

    Osmosis is special case of diffusion. Osmosis is the movement of water molecules from an area of high water potential (or concentration) to an area of low water potential through a partially permeable membrane. Water: H2O Small molecule Easily passes through partially permeable membrane Glucose C6H12O6 Big molecule Cannot pass through partially permeable membrane A partially permeable membrane allows small molecules to pass through.

    variable will be the concentration of the sucrose solution and the output variable will be the change in the potato chips' mass, the only measurements I will take will be the initial masses of all twelve potato chips, their masses after twenty minutes and finally their masses after two days.
