please will you help me - AS biology ISA experiment?
Basicallly for our experiment we had to measure how the leakage of pigment from a beetroot is affected by ethanol concentration. we used colourimeters to compare the coloursbut before we did this we placed the test tube (with ethanol and beetroot slice in it) in a hot water bath. Why was a hot water bath use for this?
Thank you in advance!
well the hotter one thing is more energy it have, the hot water helps with diffusion, and it losen up the molecules and also losen the cells up so the pigment can diffuse out of it
