Saltwater Lab

salinity irrigate Density Lab Problem: How bed a 4-layer sea pee concentration column be make? Background search: The density of urine is the weight of the wet per its unit strength, which depends on the temperature of the water. When salt is added to the water, its density increases. This is because salt has mass, and since density is mass oer volume, the density increases even though the volume does not. This makes the surface emphasis of the water greater. Surface tension is how the water molecules are held in concert in the surface forming a barrier like a membrane. It allows objects to float on the surface-- Salt can be govern into water and make layers with disparate amounts of salt. Hypothesis: If there is a balanced amount of salt, then(prenominal) the layers will be consistent.

investigate: Materials: -2 calibrated piston house -4 food intensityingings - just aboutthing to relate with -1 beaker -50 mL of water -25 mg of salt -scale to prevention salt -timer Procedure: measure 10 mg of salt in the scale and identify it in the bottom of the calibrated cylinder before putting in anything else measure 50 mL of water and put it in a beaker add 15 mg of salt to the 50 mL of water and stir it until it is completely dissolved conservatively put 10 mL of the brine in the receive cylinder with the salt in the bottom put 2 drops of food people of colour in the saltwater that is in the graduate cylinder wait about 1 minute until that saltwater layer is completely colored add 10 mL of water to the beaker that has saltwater in it so that the salinity of the water decreases. st! ir. carefully pour the water with less salt into the graduated cylinder that has the other layer(s) add 2 drops of another color to the novel layer that has less salt and wait 1 minute a second layer should me forming repeat locomote 7-9 so that more layers can be made Observations: the new layers consume some time to form the food coloring takes some time to color the water (because of the salt) layers are...If you want to pee a full essay, order it on our website: OrderCustomPaper.com
