OSMOSIS IN POTATO CHIPS 'Investigating how isotonic, hypertonic and hypotonic solutions affects the total mass of a potato chip" Aim: 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. Introduction: 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. Key words: 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...
