The purpose of the lab was to investigate osmosis‚ which was successfully achieved because there was a change in the potato’s mass which was due to the net movement of water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel

Nikhil Gopalam October Mailbox #55 Affects of Osmosis and Diffusion Introduction: Perfume spreads in a room‚ hands bloat when left in water for too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute

Abstracts The first article I read was about retirement. The article reasserted a lot if not all the points we hit on during the semester. It basically covered three different areas of retirement that need to be looked at seriously. The first being social security‚ which most of us know is looking very dim as far as our generation is concerned. The second was benefit plans offered by employers. And last was the savings that people accumulate until their retirement. The article basically tried

Diffusion and Osmosis Introduction Tonicity refers to the concentration of solutes in a solution (Lab 6-7). There are three stages of tonicity: Isotonic‚ hypertonic and hypotonic. Four unknown solutions were given and labeled as followed: Solution A‚ Solution B‚ Solution C‚ and Solution D. Since potato cells were used for this type of experiment‚ in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl. In other

our report. We give our special thanks for Wondossen Assefa‚ hardware engineer in EEPCo ICT center and Ato Seyoum‚ head of the department of the ICT center. We would like to thank our friends and families. Abstract The purpose of this report is to document what we saw and performed during the internship program. It might be helpful for sharing experiences with our friends who have been practicing in different offices all over the country. We will also try

How does diffusion affect the rate of growth? If I placed a gummy bear in various solutions‚ then the gummy bear would change in size‚ because diffusion and osmosis cause the gummy bear to react to the solution’s molecules‚ and further affects the gummy bear’s mass. An experimental lab conducted in class was tested‚ essentially to observe the effects of diffusion/osmosis. More specifically‚ according to‚ “merriam-webster.com/dictionary/diffusion‚” the process of diffusion causes particles to spread

NAME: Donna Ha TITLE: Measuring the Rate of Osmosis Using “De-shelled” Chicken Eggs INTRODUCTION: In order to fully understand the concept of this experiment‚ one must first be introduced to diffusion. Diffusion is a spontaneous process by which molecule particles move from one area that is highly concentrated to another area in which its concentration is lower. Cells contain fluids and are surrounded by fluids; in order for a cell to function it is required to be in a balanced state. The

about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis. Procecure : Part 1. Colligative Properties 1.
