In our lab‚ we were given the task of burning seven different salts and taking notes of what we observed. The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium

saltwater. Both can drown you but in completely difference ways. Drowning in saltwater is not as dangerous as it counterpart due to how easily you can recover from it. When you breathe in saltwater it goes in the lungs and sits there. Because the salt concentration of saltwater is really high compared to the cells in the lungs the water does not pass through and into the cells. The water is hypertonic so for the body to reach equilibrium with saltwater‚ water from the blood cells are sent out into

hydrated salt in order to determine the percentage of water inside of this hydrated salt. We heated up the salt in order to boil off the water‚ which allowed us to find the weight of the CuSO4 by itself. By comparing this final weight with the original weight and subtracting the difference‚ we were able to compile data about how much the weight of the hydrated salt decreased as the water gradually boiled away. In doing so‚ we were able to find the total weight of the water in the hydrated salt by subtracting

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

Analysis of Soda Ash and Carbonate-Bicarbonate Mixture Submitted: February 27‚ 2013 Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas España‚ Manila Abstract A standard acid solution like HCl can be used as titrant for the analysis of both soda ash and a carbonate-bicarbonate mixture. In the analysis of soda ash‚ the volume needed to neutralize the soda ash is used to compute for its alkalinity‚ in this experiment we obtained a 17.6 % alkalinity with an error

This shows that over time people that they studied that had a diet that contained less salt showed a decrease risk of developing cardiovascular disease. The fact that they have a few large companies on their side somewhat trying to reduce the amount of salt in their food works well to try and get others to follow. This shows that the companies that will
