• ## The Solute Concentration of a Potato

649 Words  | 2 Pages

The Solute Concentration of a Potato To find out what the solute concentration of a potato is, this shall be done by finding out the effect of Osmosis on a potato. Prediction: That if there is more water outside the potato than inside, the potato will increase in size. If however there is less water outside the potato than within, then I shall expect the potato to shrink in size. I think this because of the laws of Osmosis. Osmosis is the diffusion of water through a partially permeable

• ## Comparing the Concentrations of Saturated Solutions Experiment

1168 Words  | 3 Pages

In this lab, lab 4.3 Comparing the Concentrations of Saturated Solutions, we set out to find and compare the solubilities of two solids in water. In addition, we tested if solubility is a characteristic property of a solid in a given liquid. This lab allowed us to test and use a reliable way to measure the solubility of a solid. This lab can be replicated for any solid with the same procedure, thus it gives us a method to calculate solubility. The two solids we tested in this experiment were NaCl

• ## Concentration Camps

1428 Words  | 3 Pages

A concentration camp is where prisoners of war, enemy aliens, and political prisoners are detained and confined, typically under harsh conditions, or place or situation characterized by extremely harsh conditions. The first concentration camps were established in 1933 for confinement of opponents of the Nazi Party. The supposed opposition soon included all Jews, Gypsies, and certain other groups. By 1939 there were six camps: Dachau, Sachsenhausen, Buchenwald, Mauthausen, Flossenburg, and Ravensbruck

• ## The Concentration Of Salt Solution Affects Osmosis In Potatoes

806 Words  | 2 Pages

How the Concentration of Salt Solution Affects Osmosis in Potatoes Osmosis is movement of water through a selectively permeable membrane, from where there is a higher water concentration (or water potential) to where the water concentration is lower. In this piece of coursework I will answer the question, ‘How does the concentration of salt solution affect osmosis in potatoes?’. If you put a piece of potato into pure water, the water concentration is obviously higher

1349 Words  | 3 Pages

Measures of Market Concentration Market concentration describes the extent to which the top firms in an industry, say in the car industry where the top five firms in the UK would account for nearly 90% of the market, take up a large portion of the market share. There are various methods used to measure this, which will be discussed in turn. ‘The concentration ratio is the percentage of all sales contributed by the leading three or five, say, firms in a market.’ (Maunder, P. et al (1991)

• ## How Does Salt Concentration Affect The Mass Of Potatoes

735 Words  | 2 Pages

value is significantly less than .05 when comparing the 0% salt concentrated solution to 3% and 4%. There is also a notable difference when looking at 1% compared to 3% and 4%. This tells us that there is a significant difference between salt concentration and the mass of the potatoes that were in the water. As the amount of salt increases, the mass decreases. The reason that the differences were not significant when looking at the remainder of the tests ( 0% to 1%, 0% to 2%, 1% to 2%, 2% to 3%,
