Diffusion on a Liquid in a Liquid

Diffusion on a liquid in a liquid: In this experiment I used triplet glasses filled with tap body of piddle. All three cups mensurable the same at 15 cm from the top to the bottom. I let the piddle settle, before I started the experiment. I then(prenominal) pose wizard overleap of black food colourise into the eldest glass and waited for the food colouring to image the bottom. I forecast 96 bites. I then went to the back glass and squeezed wizard omit of the black food modify into the glass and counted 102 seconds. Finally, I made it to the third glass; put a drop of the black food saturation in and it alsok 107 seconds to puddle the bottom. I figured out the diffusion rate by dividing the cm of the glass by the time in seconds it took for the dye to reach the bottom of the glass. For the first glass it was 15/98 which equaled .15, the second glass was 15/102 which was also .15 and the third glass was 15/107 which came to .14. The average of all the glasses was .15cm/second. I moot the color of the dye does matter in this experiment, for instance I am using black food colorise. Black food food colour is way denser than someone using yellow food coloring which wouldnt be as dense. The temperature of the water does matter in my opinion. If the water is hotter is it easier for the molecules to moves, like we seen in our beet science research laboratory from calendar week two.

If we uses say lemonade verses water I think the outcome would be completely unalike. I do think a soul mood could affect this experiment. Reason be if someone was revoke they could do somet hing wrong by non paying attention, or if s! omeone is angry they could be incautious and put too much dye into a glass. deed: The effect of coarseness concentration on osmosis in potato. knowledgeableness: The purpose of doing this lab was to observe the effects that when salt is added to water in different strengths, what the effect do to the cells. Osmosis is the diffusion of water molecules across a selectively permeable membrane. In water when there is a hypertonic solution...If you want to get a full essay, rig it on our website: OrderCustomPaper.com
