Solubility of salt
...voring the increased entropy. For gasses it is the opposite because gasses when heated expand and come out of the solution. Materials : - Ring stand, rind, wire gauze, 1 400 ml beakers, Bunsen burner, beakers tongs, 10 ml graduated cylinder, balance, weigh boat test tube rack test tube holder, thermometer, & unknown salt. Procedure: - First we got all our materials together. Than we prepare the hot water bath by heating a the beaker ¾ of the way full. Than we weighted the 5.0 grams of salt on the weight boat and than placed it into the tube. After that we added 10. ml of distilled water making sure to rinse the salt from the sides of the tube. We heated it until everything of fully dissolved, than we put it into cold water and recorded the temp. When little crystal like substance started to form at the bottom. After that we did the same thing by adding 1 more gram of the unknown salt. We repeated this procedure until we reached 8 gram of salt in the tube and recorded the temp every time below is the data. Also we cleaned up perfectly after the experiment. Data : - Grams of salt/10g H2O Equivalent grams of salt/100g of H2O Solubility precipitation Tempe. 5g/10g of H2O 50g/100 of H2O 48 Degrees Celsius 6g/10g of H2O 60g/100 of H2O 53 Degrees Celsius 7g/10g of H2O 70g/100 of H2O 80 Degrees Celsius 8g/10g of H2O 80g/100 of H2O 93 Degrees Celsius Calculations : - The unknow...
