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 increased causing it to dissolve both faster, with more potassium nitrate.
Apparatus:
Bunsen burner
25g Potassium nitrate
Distilled…
