Sodium chloride

water to make a light bulb shine? It sounds crazy, but it's true! This is because salt water is a good conductor of electricity. Salt molecules are made of sodium ions and chlorine ions. (An ion is an atom that has an electrical charge because it has either gained or lost an electron.) When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water. What happens is the solution of the water…

Salt, NaCl, is a chemical compound made of sodium and chloride which has been very important to humans for many years. Salt’s ability to preserve food was the most important aspect for many civilizations. It helped eliminate the problem of only being able to eat seasonal food. Also since salt was rather hard to obtain many people used it as a form of currency. Today, However salt is almost universally accessible, while being cheap and often iodized.…

When hydrochloric acid was added to the unknown and known solutions, both resulted in no reaction. This also occurred when potassium hydroxide was added to both of the solutions. Barium chloride was then added to the two solutions, which resulted in a cloudy white precipitate from both of the solutions. A cloudy white precipitate also formed when calcium nitrate and ammonium nitrate were added to both the unknown and known solutions. These…

A similar experiment such as the reaction of Sodium Thiosulfate and Hydrochloric Acid includes the “Yellow Snowstorm” reaction – a reaction between Copper (II) and Thiosulfate. Copper (II) sulfate [CuSO4·5H2O] dissolves to give cupric ion (Cu2+); in the context of a redox reaction with thiosulfate, the cupric ion acts as an oxidizing agent. Reactions within the temperature on Sodium Thiosulfate and Hydrochloric Acid occur as the result of molecules interacting with each other to create new…

produces soap usually from the base hydrolysis of a fat or oil is called saponification. It is also known as soap making. Formerly, it is the reaction between an ester and sodium hydroxide to yield sodium stearate. The beef was used as triglyceride by boiling it with lye or an impure sodium hydroxide. The top layer is the sodium stearate wherein once it was cooled and turned into solid it was chopped into cubes of yellow soap. In addition, lye was traditionally made by the process of pouring…

environment the student had, was water and sodium chloride. In this instance water was the model cell (what was in the dialysis tubing) and Sodium chloride was the surround environment (plastic cup). The initial weight of the model cell was 13.2g, but after sitting in the sodium chloride solution over night the cell lost water and only weighted 11.6g. Since the solution of the model cell- in this case water- left the cell and entered the surrounding Sodium Chloride it meant the cell had a…

Introduction Unknown substances can be found everywhere. Whether it is the mysterious crust on the desk, or the sticky material found at the bottom of an unwashed bowl, there is a curiosity as to what that substance could be. In science, the unknown substance is called the analyte (1). The unknown substance, taken from the Gulf of Mexico, is tested to determine the true identity of the substance. In order to find the analyte, there are two different scientific methods that can be applied. The…

Phenols Degradation by Fenton Reaction in the Presence of Chlorides and Sulfates Siedlecka et al. (2005) also studied a series of phenol compounds present in wastewater. These compounds, as mentioned above, are widely used therefore are commonly found in wastewater derived from different industries such as petrochemical, food or resin manufactured. Since common biological treatment for these kinds of compounds is not feasible, is important to develop new technologies to treat these…

properties of Sodium Chloride, being that it is not Hygroscopic, Efflorescent or Deliquescent. Thus, based on this experiment solely, it is not ensured that the salt is Sodium Chloride as 3 other salts share this…

the reaction of sodium carbonate and calcium chloride dihydrate (the dihydrate must be included with the molar mass calculation)? Predictions: Predict the mass of sodium carbonate and calcium chloride dihydrate that will be required to produce 1.90 grams of calcium carbonate: Therefore, the predicted mass of sodium carbonate is 2.0 grams and the predicted mass of calcium chloride dihydrate is 2.8 grams. Materials: 2 Beakers (150 mL) Calcium chloride Sodium carbonate…
