we have found out about the role of positive and negative charges that are useful in order to conduct energy. Simultaneously‚ we have also found out that saltwater conducts energy because of the solid salt it contains and when it is dissolved into water‚ the elements sodium and chloride from the salt separate or break up because of the very reactive traits of water (H2O)‚ thus‚ causing the production of positive and negative ions that are able to carry energy and consequently conducting electricity

The primary focus of experiment 4 was to teach a student the basic solubility rules of salts in aqueous solutions. After developing and using a scheme for the qualitative analysis of three cations in an aqueous mixture‚ a student would use a centrifuge to identify‚ precipitate‚ and separate the three ions in the mixture. After becoming familiar with all three cations‚ the student would use the scheme again to identify at least two of the cations in an unknown solution. In order to begin the separation

Sodium chloride is table salt that is commonly used in the food industries as a flavor enhancer and preservative society. Sodium chloride is also used in glass production in society. Salt helps lower the melting points of ice or snow‚ therefore they are used in cold climates to help get rid of accumulating snow or ice. Sodium chloride is normally made by

Erica Mitchell Mr. Vredenburgh Period 5 52/55 The Effect of Carbon Dioxide on Salt Water Abstract Background: The human population strongly relies on the oceans for food‚ transportation‚ recreation‚ climate regulation‚ and half of the Earth’s oxygen. These oceans‚ that we rely so heavily on‚ are becoming more acidic and less hospitable‚ making ocean acidification the world’s second most important atmospheric carbon problem. This carbon is released into the atmosphere by burning fossil fuels

many Americans experienced on the day that the Japanese bombed Pearl Harbor. But what people want to know is why. Well right after World War I‚ a peace treaty was created and the League of Nations was established. But the Japanese saw the treaty as a way for the countries like France‚ England‚ and United States to keep the power for themselves and not only that they invaded China. So the real reason why Japan bombed Pearl Harbor was because they plan for a new world order‚ the lack of oil Japan was

Extracting NaCl from Rock Salt and assessing its purity Aim The aim of this experiment was to obtain a pure product from a solution through the processes o extraction‚ filtering and evaporation. Introduction Extraction is used when trying to separate or purify a product. For an extraction to be successful the substance used to make the solvent should readily dissolve. The substance used in this practical was rock salt. The liquid used should not react with the substance that needs extracting
