Properties of Water Lab Part A. Observations: When Copper Chloride was mixed into water the Copper Chloride started as small crystals in the bottom and sides of the test tube, but once shaken they completely dissolved into the water. When Copper Chloride was dropped into the alcohol it seemed to clump together and sink to the bottom, when shaken lightly or even vigorously the crystals of Copper Chloride simply moved around but retreated back to the bottom of the test tube when left still, it did not mix at all. Questions: 1. When Copper Chloride is added to water and shaken vigorously the copper Chloride completely dissolves leaving a pale transparent blue solution. 2. When Copper Chloride is added to substance X and…show more content…
1A-Water/MSG: When shaken the water and MSG they mostly dissolve creating an orange gold color, the substance foams at the top from the vigorous shaking action yet still some MSG residue remains at the bottom of the test tube, it was unclear if the reason was because we did not mix it enough or rather we added too much MSG to the amount of water given. 1A-Alcahol/MSG: These two substances barely mix together leaving a transparent yellow tint to the alcohol as well as MSG that was unable to dissolve at the bottom of the test tube. We concluded that this residue was unable to be dissolved in this liquid because the amount of MSG remaining in the bottom of the test tube was around the same amount that was originally placed into the alcohol. 1B- Alcohol/Vegetable Oil: Created a foamy top layer, was semi unclear but as to the best of my observations the alcohol nearly completely dissolved the oil, leaving a foggy appearance to the once clear…show more content…
With only a swift small movement side to side the detergent completely dissolved into the alcohol creating a discolored substance. The oil added to this mixture later on simply went straight to the bottom. Water/ Detergent: Sinks to bottom as well. When shaken the detergent it completely dissolved but unlike the alcohol this mixture creates suds and a muggy discoloration to the water. The oil later added simply stayed in the middle between the liquid and the suds at the top. Analysis: 1. The substance MSG is water soluble, it completely dissolved when added to water, but was not soluble in alcohol. 2. Vegetable oil is hydrophobic and there for is not water soluble but alcohol on the other hand is completely soluble with vegetable oil. 3. We know from observing the vegetable oil and water together that the relative density of water is greater then the density of vegetable oil because the oil will always recede to the surface of water. 4. Emulsification agents allow for two unbendable liquids to be combined, the detergent hold properties that both substances can in return blend with leaving detergent dissolving in both the water as well as the alcohol unlike other substances we tried to
