The effect of temperature on solubility of green treat was demonstrated. This was done by dissolving the table season in distilled peeing at different concentrations and finding the temperature at which crystallisation occurred. From this a solubility curve could be formed. It was found that as the temperature increased, so did the solubility of potassium nitrate in distilled water. At 50?C our results indicated a solubility of 89 g/100mL of pee which was close to the known solubility of 80 g/100mL.
debut:
When a salt, such as potassium nitrate or sodium chloride, is placed in water a dissolving reaction will occur. At first, the optimistic and negative ions of the salt compound ar only attracted to each other. In swan for the salt to dissolve, these bonds must be broken so that the ions divorce from each other.
In the water molecules, hydrogen is slightly supreme and oxygen slightly negative so they are attracted to ions of the frigid charge, known as dipole attraction. These water molecules break away the bonds of a salt by surrounding themselves around the salt ions, with the opposite charges facing each other. Whether or not a salt dissolves is determined by which attractive force is stronger, the immanent ionic force or the attraction for the ions from the water molecules (Ophardt, C., 2003).
kilobyte nitrate (KNO3) contains negative nitrate ions and positive potassium ions. When potassium nitrate is placed in water the slightly positive hydrogens in the water molecule are attracted to the nitrate ions and the potassium ions are attracted to the slightly negative oxygen. insure 1 shows how sodium chloride would bond when placed in water.

The solubility of a solute in a solvent is affected mostly by the temperature. A solubility curve (as seen in experience 2) shows how the solubility of a solute varies with the temperature of the solvent.
