OSMOSIS IN POTATO CHIPS
'Investigating how isotonic, hypertonic and hypotonic solutions affects the total mass of a potato chip"
To find out how changing the concentration of salt solution affects the total mass of potato chips, placed in it. So we are investigating the movement of Osmosis through a selectively permeable membrane, in this case potato.
I am carrying out an investigation regarding Osmosis in potato chips. In order to conduct my investigation I will need to fully understand all the background information I know. Using secondary sources such as textbooks, CD Roms, library, class notes and the Internet.
Isotonic: The solutions being compared have equal concentrations of solutes. E.g. 20ml water + 20ml salt sol.
Hypertonic: The solution with the higher concentration of solutes.
Hypotonic: The solution with the lower concentration of solutes.
Osmotic pressure: Diffusion of water across a membrane - osmosis generates a pressure called Osmotic pressure.
Osmolarity: Used to describe the number of solute particles in a volume of fluid.
Plants in general
Plants need water to grow. Plants use water to aid them
