One way you can separate the powders is Solubility in water. use 10ml of water and a little bit of the powdered solid, and shake to determine if soluble or insoluble. if it is soluble you can do the evaporation test to see what was left and continue to test that to find the unknown substance. you can also repeat with alcohol. Another way you can separate the powders is by finding the micro melting point. all powders that are completed in trash or down sink. turn in data sheets and wipe down desk.]]> 2019-01-14 14:50:21 UTC https://padlet.com/zrouelda/ee06t4ud0iyw/wish/320315517 zrouelda https://padlet.com/zrouelda/ee06t4ud0iyw/wish/320316283 To identify our metals we are going to use density, acid, and magnet tests. For density we are going to weigh our metals in grams and then find out its volume. Find the volume we will fill the graduated cylinder enough to have the metal completely submerged. We will then see how much the water rises and find the difference which will be the volume measured in meters. First we have to clear the test tube then hand it to your teacher or proctor. Next we must find and test all the metals (Don't forget to return them), Then start fractional and normal distillation. We have to save all powders in our drawer and rap them in tin foil (label them with sludge # and initials). Save all liquids in test tubes then put them on your teachers desk. Finally hand in all data sheets.]]> 2019-01-14 14:51:37 UTC https://padlet.com/zrouelda/ee06t4ud0iyw/wish/320316283 zrouelda https://padlet.com/zrouelda/ee06t4ud0iyw/wish/320600394 Before you begin you must finish fractional distillation. Then test liquids an dump them out when finished. Next you must separate and begin the powders. Label and finish powders. Then you have to go put all the powders in the drawer. clean up and finish up your lab. Finally hand in all data sheets]]> 2019-01-15 02:37:43 UTC https://padlet.com/zrouelda/ee06t4ud0iyw/wish/320600394
