The Water Salt Water Solution

When observing the properties of water, we see liquid freeze into a solid all the time in our everyday lives. For instance, something as simple as putting a bottle of water in a freezer freezes the water into a solid in a few hours, or even a pond can be frozen over in the middle of a harsh winter. Molecules of water or H2O are proven to freeze at a temperature of 0°C, but what is puzzling is that when looking at the ocean, the waters do not freeze no matter what the temperature is outside. The reason the ocean does not freeze is because it is not pure water, but a solution of NaCl and H2.O, also known as salt-water. The ocean salt-water solution actually has a freezing point of -2°C, but if a salt water solution is saturated it freezes at…show more content…
Before the experiment was started, goggles were put on in order to protect our eyes from any accident with the solutions, and a chemicals utilized table was acquired to fill out throughout the experiment. To start, a water beaker bath and an ice beaker bath were prepared. The water beaker bath was placed on a hotplate. Then 5.00 grams (plus or minus a hundredth of a gram) of tert-butanol was obtained and put in a large test tube. Then a thermocouple connected to a LabQuest was positioned in the sample. The test tube was balanced in the water bath with the tert-butanol below the water level and the hot plate was turned on. The water bath was heated until the thermocouple read above 50 °C. Once the sample was above 50 °C, the LabQuest was set to record temperature data at 10 samples per minute. After some data was gathered, the sample was removed from the water bath and positioned in the ice bath. Once the temperature measurements steadied for a few minutes and there was ice formed in the test tube, the trial was concluded. Three more trials were performed using different amounts of additive substances. The tert-butanol sample from the first trial was reused for the second trial. Then the additive substance for each of the three other trials were added to a 5.00 ± 0.01 gram sample of tert-butanol and the above
