The Solubility of Potassium Nitrate Aim: The aim of this experiment is to find out by how much the solubility of potassium nitrate into distilled water increases when the solution is heated, and if yes, by how much. Hypothesis: According to data on the internet, 3.75 × 10­¹ moles of potassium nitrate dissolve in 100g of water. I believe this information may be correct. I also believe that as the solute is absorbing outside heat, the energy is …showed first 75 words of 717 total…

Human error can be reduced by having the same person take all the readings and observations. Another problem could be any water evaporating from the boiling tube, which could result in inaccurate readings. Unfortunately there is no way of eliminating this error that I can think of. One should simply state that the results are approximate.
