3. As the temperature rises, the solubility of KNO3 also rises
4.
Temperature C | Your data KNO3 in grams per 100 ml of H2O | CCZ data KNO3 in grams per 100ml of H2O | 35 C | 49 | 49 | 35 C | 49 | 49 | 70 C | 135 | 180 |
5.
Data pointGrams of KNO3 in grams per 100ml of H2O at C | Your data saturated, unsaturated or supersaturated | CCZ data saturated, unsaturated or supersaturated | 75g of KNO3/100g H2O at 40 C | Saturated | Not saturated | 60g of KNO3 /100g H2O at 50 C | Not saturated | Not saturated | 80g of KNO3/100g H20 at 60 C | Super saturated | Not saturated |
6. The CCZ graph data in comparison to the data from my graph is not too far off. In some places the graph is either up by 10 or down by 10 at the max.
7. According to my graph 120 g of KNO3 will not completely dissolve in 100ml at 40 C because the temperature would have to be at least 69 C for it to dissolve completely.
8. In order to make a saturated solution at 55 C you must have 70 g of KNO3
9. You would need about 14g at the min. to grow a crystal. For best results the temp. Should be heated up to 20 C to get that KNO3 to crystallize. Certain solutions grow different things due to the amount of chemicals and heat is applied.
10.
Conclusion: In conclusion we found that the more KNO3 you add the shorter amount of time it takes to crystallize. The less amount of KNO3 you have, the longer it takes to crystallize. In the end, my hypothesis was correct because when we added more KNO3 it took less time to crystallize. We had 0 errors in our lab everything went
