it's about a lab we did on osmosis...?

Question

where do substances that are really concentrated tend to go? i actually don't thoroghly understand he question. please explain to me ASAP!!!

Answer 1

The easiest way to understand osmosis is to think about a bottle of strong perfume. When you take the lid off the molecules spread out filling the room slowly with smell. Molecules move from an area of high concentration to an area of low concentration. (that is your answer, I believe) Another way to understand it is to drop food coloring into a large bowl of water. It will slowly spread throughout the bowl.

Answer 2

The other answerer is describing diffusion. Osmosis is referring to the passive movement of water from a high water concentration to low conc of water. This is generally the reverse of you may think in concentration. If you have a low concentration of salt in a bowl of water, and introduce into it a semi-permeable vessel (one which allows only water and not salt across ) such as a cellulose tube, with a high concentration of salt, then water will attempt to equalise across the membrane and move from the high concentration of water (in the bowl) to the low concentration of water inthe tube. What is most confusing is that people find it difficult to grasp the concept of water concentration, as this is usually used as a point of reference (ie used to dissolve things into).

Hope this helps
