WebOsmosis Practical. 2/ Preparing the Potato discs Using the cork borer provided cut several bores of potato. Cut the bores into discs with a scalpel keeping the thickness of discs even. Lay the discs on absorbent paper, cover with the paper and press gently to remove surface moisture. Prepare a set of discs for each Petri dish. WebI think this because of the scientific theory of ‘Osmosis’. This is the theory that states when a concentrated item (in our case a potato chip) the sugar concentration within that will move out to the more concentrated position. I think that as the sucrose is added to the beaker, then the potato chip’s sugar concentration ...
