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

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

also known as salt‚ common salt‚ table salt or halite‚ is an ionic compound with the formula NaCl‚ representing equal proportions of sodium and chlorine. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. /Salt is currently mass-produced by evaporation of seawater or brine from brine wells and salt lakes.

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

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
