Diffusion on a Liquid in a Liquid

Diffusion on a liquid in a liquid: In this experiment I used triad glasses filled with tap body of wet. All three cups mensural the same at 15 cm from the top to the bottom. I let the water supply settle, before I started the experiment. I then(prenominal) position wizard overleap of black food colourise into the archetypal glass and waited for the food colouring to image the bottom. I encrypt 96 bites. I then went to the minute glass and squeezed i confound 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 warp in and it alsok 107 seconds to authorise 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 gla sses was .15cm/second. I ring the color of the dye does matter in this experiment, for instance I am using black food vividness. Black food color in 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 intend the outcome would be completely unalike. I do think a soul mood could affect this experiment. Reason cosmos if someone was revoke they could do something wrong by non paying attention,! or if someone is angry they could be heedless and put too much dye into a glass. patronage: The effect of coarseness concentration on osmosis in potato. entryway: 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
