Salt and Ice; Minnesotas Battle Abstract Salt is applied in the thousands of tons every year to reduce ice and‚ in turn‚ reduce accidents on Minnesota roads. When the ice and snow melt each spring‚ the majority of this solution is relieved into rivers and lakes through storm drains on Minnesota roads. The salt negatively affects fish and aquatic plants by dehydrating them and altering fertilization. The damaging effects of sodium chloride are long term and not easily repaired. The Minnesota

are carrying out an investigation to find out how different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house

supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity‚ mechanically using centrifugal force‚ or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater. This experiment aims to determine the effect of initial concentration and initial height of the slurry on its settling

Hand-out 3: Market Concentration Specification Market concentration. Definition “’Market concentration’ is the degree to which the output of an industry is dominated by its largest producers.” In other words‚ how many of the sales in the market are accounted for by the biggest firms in that market.

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

Add potato chip & close bung. 7. Take measurement of gas after 2 minutes. 8. Repeat. Investigating the effect of enzyme concentration on the rate of an enzyme-catalysed reaction. James Moore Conclusion: For the conclusion we see that in fact the hypothesis is correct. When independent variable increases so does the dependent variable. As the amount of enzyme concentration increases so will the rate of the enzyme catalysed reaction. In the human body substrate is always available

The litmus paper and the pH probe determined the salt solutions’ pH levels. When the blue litmus paper was dipped into ammonium chloride‚ the paper was changed to red whereas the red litmus paper stayed the same indicating that the solution was acidic. PH levels shown through pH probe also ranged between 5.5 to 6.0. Yet when in the presence of sodium acetate blue litmus stayed blue whereas red litmus turned blue‚ indicating its basicity. pH probe also showed the solution’s pH varied between the

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

Experiment 2: Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins
