Saltwater Lab

salt irrigate Density Lab Problem: How posterior a 4-layer sea weewee assiduity column be make? Background search: The density of body of piddle is the weight of the water per its unit wad, 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 contrary amounts of salt. Hypothesis: If there is a balanced amount of salt, whence the layers will be consistent.

investigate: Materials: -2 calibrated piston house -4 food colouringingings - 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 graduate 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 cautiously put 10 mL of the brine in the receive cylinder with the salt in the bottom put 2 drops of food change in the brine that is in the graduated 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 th e water decreases. stir. 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 recent layer that has less salt and wait 1 minute a second layer should me forming repeat stairs 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 piss a full essay, order it on our website: OrderCustomPaper.com
