Introduction: Copper(II) sulphate can easily be prepared by reacting copper(II) oxide with dilute sulphuric acid. The resulting copper(II) sulphate solution when cooled can easily crystallize, so the amount of the product can be accurately measured. This lab result can then be compared to the theoretical amount to give a % of the yield calculated. The then Copper(II) sulphate crystals are CuSO4.5H2O. Hypothesis: It is my opinion that the results we …showed first 75 words of 860 total…

…showed last 75 words of 860 total…everything to be filtered. -Extension: If I were to do the experiment I would change various things throughout the experiment to get better results than this time. This would include using bigger filter paper so nothing would leek over or crystals would not fall onto the table while drying. Be more careful when moving the crystals or solutions, do the experiment in a different lab where not as many apparatus mistakes would or could happen.
