How Osmosis Affects The Weight Of Potato Chips

Aim: To investigate how duration of dripping affects Osmosis in white stump spud vine create from raw material.

Background scientific Information: In Osmosis is the movement of pissing from a devote of high water concentration to a place of grim water concentration through a partially semipermeable membrane. This osmosis movement get out continue until the water potential on both sides of the ppm is balanced. When a potato chip is put in plain water, it depart become larger, due to osmosis, as the water potential is more than that inside of the chip, so as a result the potato is storing more water and expands in size. that when sodium chloride is added to the solution, the water potential is higher in the potato than in the salt solution so as a result the potato shrinks. The change in potato tissue depends o the substance if any, added to the water. If say sugar were added unlike with salt it would expand. This is because sugar is the potatoes fuel that it uses as energy so it will be trying to absorb as much as possible.

Key variables: In this experiment we shall be testing duration of soaking so we shall focus on the change of time and lading of potato. But in order to notice the effect of time on the osmosis rate we must ensure to keep the by-line variables the same:

Size of chip. These will all be the same burtheniness as they will be cut down by the potato chipper, the length will be measured with a ruler, and cut with a knife.

Weight of chip. All chips will start with the same weight which will be determined using a measure scale and measured to the nearest 0.1 grams.

Solution concentration. In each vitrine we shall measure 50ml of distilled water and combine it with... is a professional essay writing service at which you can buy essays on any topics and disciplines! All custom essays are written by professional writers!

I did this lab when I was in grade 11 Biology. It was fun, but there are better.

The tables for your results became messed up when pasting here, but that is not your fault.

Anyways, the essay, or I should say lab, was very(prenominal) well done. You covered the key points as well as presenting some background information.

Finally, this depends on your teacher, but my teacher will dock marks for first person pronouns in a professional lab. So, its up to you and your teacher.

Overall, it was good. I hope you get a good mark :P
