Osmosis Investigation

Osmosis Investigation

Aim

In this investigation I aim to find soaking up of a potato booth. I get out do this buy set slices of potato in to different concentrations of sugar seclusions so we may find the concentration that is isotonic with potato cell sap. A piece of potato in such a outcome depart neither gain nor lose any tip.

Hypothesis

My guess is that the isotonic point will be between the 80 and 120g/l. I predict this because I move over done a preliminary experiment that suggested this is where the isotonic point lay. I simulate that the potato chip in the 50g/l will incur turgid and gain in weight because the chip will have a lower concentration than the piss and it will take in the water to make the water molecules the aforementioned(prenominal) inside as the outside of the chip. The potato chip in the 90g/l will become flaccid and lose weight because outside the chip there is a high concentration of sugar and the chip will give out water to make the water concentration outside equal to that on the inside of the chip.

Scientific background

This information is from web.ukonline.co.uk

Osmosis is a special form of scattering:

the MOVEMENT OF WATER

from a dilute solution to a to a greater extent concentrated one

through a PARTIALLY PERMEABLE MEMBRANE.

This type of membrane (also called semi-permeable) allows only water, scarcely not other (dissolved) substances to pass through.

All cells argon surrounded by a cell membrane, which is partially permeable, and the cytoplasm contains dissolved substances (solutes), e.g. sugars, salts, proteins. Whether or not water enters or leaves the cell depends on the relative concentrations of the cytoplasm and the fluid surrounding them.

Method

I have conducted a previous experiment of this but it was not accurate, but I found that that...
