Analysis The trend that my graph and results show is that when the potato was placed in a solution that had a higher concentration than the chip itself‚ the potato lost weight (0.4‚ 0.6‚ 0.8 and 1.0 molars). In the same way when the potato chip was placed in a solution that had a lower concentration than itself‚ the potato chip gained weight (0.0 and 0.2 molars). For my results I calculated the percentage gain/loss in weight using the following formulae: Average change in weight/weight at

Case Study : Morton Salt 1. Briefly describe salt production‚ from brine production to finished round cans. Salt is obtained by introducing water into salt caverns which in turn dissolves the salt deposits within the caverns‚ allowing the salt solution (brine) to be brought to the surface for further processing. The brine is boiled in order to remove most of the liquid‚ resulting in salt crystal deposits. The salt crystal deposits are then further dried to remove all residual moisture to produce

effect of surface area to volume ratio on Osmosis As far as living organisms are concerned‚ they are all made up of cells whereas‚ the membrane surrounds all those cells. The cell membrane has the key responsibility to maintain a stable interval environment. Even though‚ Cell membrane is made up of phospholipids bilayer and has that great amount flexibility making it unbreakable while transportation of substances. However‚ certain substances such as‚ dissolved gases‚ sugars‚ salt and liquid find it difficult

investigation into the rate of osmosis Liana Gohery - 98332250 12/12/2014 Word count - ………3000……….. 1. Abstract This study was conducted to investigate the effect of concentration gradients on the rate of osmosis. Osmosis is the cellular transport of water‚ this study was conducted to show the significance of the rate at which this occurs. Dialysis bags were filled with three different concentrations of sucrose solutions and two with water. They were then completely immersed in water
Premium Osmosis Diffusion Chemistry
Diffusion‚ Osmosis‚ Active Transport There are two ways in which substances can enter or leave a cell: 1) Passive a) Simple Diffusion b) Facilitated Diffusion c) Osmosis (water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms‚ ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion

How Do Different Factors Affect Osmosis Aim: To discover The Different factors that affect osmosis. Factors that affects the rate of osmosis in a potato: * Time * Temperature * Molar * Sucrose solution * NaCl solution * Concentration of liquid * Age of the potato * Variety of the potato * Potassium‚ K(AQ) Factor Chosen: Different Molar of Sucrose Solution In this investigation I will change the molar of sucrose solution to find the increase or decrease

Canada is not only one of the biggest economies in the world but also one of the richest nations. Like the other developed nations‚ the Canadian economy is dominated by the service industry‚ which employs about three fourth of the Canadian working population‚ but‚ unlike the other developed countries‚ Canada gives a lot of importance to its primary sector. Canada also has the eighth largest commercial fishing and seafood industry in the world. Though the Canadian economy is closely integrated with

Differences between colonies: Religious: The Pilgrims who settled at Plymouth were "Puritans" vs. Anglicans at Jamestown. Plus‚ Plymouth was founded for religious reasons while Jamestown was founded for economic reasons. Don’t get me wrong--religion was critical for both groups but the Puritans left England because they were religious outcasts while the settlers at Jamestown were there for economic benefit and had investors. Labor: Jamestown was initially settled under martial law and the military
