Blank 1 Blankity Blank Blankity Blank Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment‚ you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid‚ the temperature at which that liquid freezes decreases‚ because the molecules of the solute become attached to the water molecules‚ making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing

falls‚ making you liable for injuries. So most people rely on deicers such as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete.

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

if an egg will float in salt water. The question is how much salt is needed to be added to the water to make the egg float. The problem is that no one knows how much salt is needed to make an egg float. Hypothesis It will take at least three teaspoons of salt to be added to the water for the egg to float. The reason why I think three teaspoons of salt will need to be added to water for the egg to float is because the egg a density that is lower than the density of the salt water.

Lake Chad: almost gone Straddling the borders of Chad‚ Niger and Cameroon in West Africa‚ Lake Chad has been a source of freshwater for irrigation projects in each of these countries. Maps drawn from a series of satellite images show a dramatic decrease in the size of the lake over the past 30 years. Since 1963‚ the lake has shrunk to nearly a twentieth of its original size‚ due both to climatic changes and to high demands for agricultural water. Since 1963‚ the surface area of Lake Chad has decreased

Can salt change water’s density? I conducted an experiment using common household items to find an answer to my question. The procedure involves filling two cups with two hundred fifty milliliters of water. Then‚ mixing teaspoons of salt in water one at a time‚ until you’re able to submerge a raw egg in the solution and have it float up. My hypothesis is‚ salt does infact change water’s density‚ and if the egg floats it’s proof of density change in the water‚ because it must be less dense than the

Do clean lakes really exist? By Yujia‚ Luo (Group 1) September‚ 2014 Introduction A main purpose of wastewater and sludge treatment is to remove phosphorus (P). It seems to be reasonable because excess phosphorus entering the aquatic systems can result in algal blooms. People have been taking much effort to explore simple‚ economic and high effective methods to remove phosphorus. Concentration of nitrogen (N) is another important element to assess the quality of freshwater. As the same with phosphorus
