Lab-Potassium nitrate(KNO3) in water

Chemistry Lab- KNO3 in piddleTo start with, I want to asseverate that this is not a normal lab report, but scarce nigh raw data. Another thing is that the conclusion isnt precise forward-looking and can be improved inn many an(prenominal) ways. We make a lab where we were supposed to lift bug out at what temperature honey oil process (KNO3) was solved in weewee. To do this, we ask a beaker, test-tube, weighing scale and something to tot the water temperature with. We started by putting in an substance of grams of green nitrate (KNO3) in a test-tube. Thereafter we poured some a constant core of water (H2O) in the test-tube, which in this sheath was 4 ml. We past put this test-tube in a beaker fill with boiling water (H2O) so that the kilobyte nitrate (KNO3) was solely solved. We had a ?temperature-checker? in the test-tube all the time. It would have been very bad for us to find an undefiled temperature value of we had been checking to see when the Potassium ni trate (KNO3) was solved, since the temperature increases very fast.

This pass on not be a problem if we rather check the temperature when the Potassium nitrate (KNO3) is change down, (and the atoms of it becomes more permanent so it becomes a solute) because that process will take practice at a slower locomote and you will therefore find a more accurate temperature. And that is what we did. The first amount of Potassium nitrate (KNO3) that we mixed with 4 ml of water in the test-tube, was 2 g. This showed that the temperature it takes for 2 g of Potassium nitrate (KNO3) to solve in 4 ml of water (H2O) is 21 degrees. And we kept on like this and merely changed th! e amount of Potassium nitrate (KNO3)... If you want to get a full essay, set out it on our website: OrderCustomPaper.com
