The Solubility of kibibyte treat Aim: The aim of this examine is to find pop by how much the solvability of grand treat into distilled peeing increases when the solution is heated, and if yes, by how much. Hypothesis: According to info on the internet, 3.75 × 10¹ moles of thousand nitrate answer in 100g of piddle system. I believe this development may be correct. I also believe that as the solute is absorbing egressside heat, the readiness is increased causing it to dissolve both faster, with more jet nitrate. Apparatus: Bunsen burner 25g Potassium nitrate Distilled water stewing tube Clamp Thermometer Method: 1) Weigh out 25g Potassium Nitrate into a grinding tube. 2) score 10ml water 3) spark solution over bunsen until potassium nitrate dissolves, woful the tube in and out of the flame so it doesnt grind over. 4) Allow to cool and record temperature at which crystals appear 5) Add 5ml of water and repeat steps 3) and 4) 6) Repeat step 5) until you d o 30ml of water in the boiling tube 7) Transform data so it is verbalized as a mass of potassium nitrate per 100g of water. 8) Graph Results: Water (ml)Temp at which crystals appear ( C)Potassium Nitrate (g) per 100g of water 10101250 1599166.6 2097125 2595100 309383.
3 Mass of potassium nitrate fade away at 40 : 64g Mass of potassium nitrate fade out at 80 : 169g Mass obtained as crystals when solution cooled from 80 to 25 : 134g or 79.3% Two graphs: one(a) from the internet, one made jibe to our results. Conclusion: From the results we can see that the solubility of potassium nitrate is increased as the temperature is increased. The relationship ! is nonlinear, which gist it doesnt form a straight line when plotted on a graph. Now, in that location are three... If you want to get a full essay, nine it on our website:
