Osmosis-practical?

Post by mi_blacktea » Wed Nov 07, 2007 3:31 am

OMGSH THIS PRACTICAL IS EATING ME ALIVE!!!

so.um my aim for the experiment we have to carry out it to: determine the effect of change in surface area on the rate of osmosis reaction.

controlled variables: temperature of the room, concentration graident, pH, mass of water.

i have no idea how to do the experiment >.< i have to write out my own design and such. can someone help? :( i'm an IB diploma student.

THANKS A LOT! :D

If you have a membrane and a pH gradient, you would have water flow.
