The areas of high solute concentration gave water more places to go, moving them into and out of the membrane depending on the amount of solute in the solution.]]> 2016-10-02 18:08:58 UTC https://padlet.com/lisle202/651u3c306b4z/wish/127741391 Reflection nm18128 https://padlet.com/lisle202/651u3c306b4z/wish/127741412 If I were to do more experiments to prove this concept I would use different substitutes for membranes and compare times, or use a different solute to see if the results would change. ]]> 2016-10-02 18:09:08 UTC https://padlet.com/lisle202/651u3c306b4z/wish/127741412
