Chloride

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…

change in temperature of 8.5*C and a theoretical change in temperature of 1.03*C. The percent error for this additive was 8.1% error. My hypothesis was,If the freezing point depends on the number of ions in a substance, then the chemical aluminum chloride will have the greatest impact on the freezing point because it has the maximum amount of ions. My hypothesis was not supported because, NaCl is the additive that had the greatest impact on the freezing point because the concentration of 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…

worked and caffeine was isolated we used thin layer chromatography (TLC) to compare the extracted material to a standard solution of pure caffeine. We dissolved the sublimed caffeine in 3 mL of methylene chloride in a clean vial and then swirl the residue in the flask with 3 mL of methylene chloride. A pure caffeine solution sample was obtained. On a chromatographic plate, two lines were drawn 0.5 cm away from the short ends. Then place one drop of the caffeine solution on the line and next…

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…

how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the water. The constants are the surface being tested on which is a stove, the amount of water being used, the amount of grams used for the sodium chloride and the sucrose, and the time that is set for the water to heat up. What is controlled…

disposal, in the chemistry lab, the chemicals sodium chloride, in both chip and powdered form, and hydrochloric acid. Michael decides to mix the two substances by pouring the hydrochloric acid on the sodium hydroxide in both states chip and powder form. Michael does not have an aim or reason for doing this so his intentions are unknown. Michael gives a possible outcome or hypothesis that as soon as the hydrochloric acid is added the chips of sodium chloride would react instantaneously and quick…

more efficient. It is then extracted using dichloromethane (DCM) and maceration. The chlorophyll and β-carotene pigments are dissolved into the organic DCM layer which is polar and does not mix with water. The solution is then washed with sodium chloride (NaCl) to draw out any remaining water left in the solution that was not dried out by the ethanol. [1] Water will move toward the more hypertonic solution and separate from the DCM extract. After successful separation of the pigments from the…

harsh or lye-heavy. This means that it is non-reactant to oils and can burn or irritate the human skin. After the saponification process, sodium chloride or table salt was added to precipitate the soap because soap is less soluble in salt water. This resulted to the appearance of excess bases which was floated in the solution. Also, the role of sodium chloride made the solution viscous. The solubility rule, which means like dissolves like, results to the cleansing action of soap. The polar head…
