Experiment with beetroot cells.

Post by bottlegreen » Sat Feb 19, 2005 10:09 am

Hey guys,

Soon, I will be doing an experiment by immersing fresh beetroot slices in NaOH and vinegar. I have a few questions that I need answering beforehand:

- What influence you think differences in surface area of the slices might have had on this experiment?

- What influences do you think differences in thickness of the slices may have?

- What would you expect to happen to the beetroot slices if, instead of using vinegar or NaOH, you had used solutions of pH from 6 and 8?

Thanks in advance.

John.

For the first two points - It affects how easily the beets absorb the solution.

Thirdly, the vinegar and sodium hydroxide have powerful pH levels. The substitutes would be more neutral and the reaction seen should be milder.

:o If you have washed the beets before hand, submerging them in any form of acid like vinigar (CH3COOH) will increase the pH levels near the beets, due to part of the end product being H3O.
