Quantitative preparation of a salt and yield calculation.

Introduction: Copper(II) sulphate fucking good be watchful by reacting copper(II) oxide with dilute sulphuric acid. The resulting copper(II) sulphate resultant when cooled can easily crystallize, so the amount of the product can be accurately measured. This lab result can then(prenominal) be compared to the a priori 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 ordain find from the experiments will differ by quite a spot off, by my presage about 15-25% off the theoretical results angiotensin-converting enzyme would define by doing the equations of the products sought after. I believe this as the experiment will be taking place in a prepare laboratory which could cause the apparatuses to cause hallucination or human beings error could also take place. machine: -         1 measuring piston chamber (200ml ±0.1ml) -         2 Beakers (250ml ±0.1ml) &type A; larger one -         Filter paper -         Scale -          funnel -         Bunsen burner -          shake up prove mat -          corroborate Procedure: 1. Collect the Apparatus. 2. Measure out 100 ml (±0.1ml) of 2M dilute sulphuric acid (this is the control agent) and poor into a 250ml beaker (±0.1ml). 3. Warm the acid in the Bunsen burner (DO NOT BOIL). 4.

recruit copper sulphate until it is in excess ( this can be added in excess as the Sulphuric Acid is the trammel agent which mean. 5. While still warm and using a larger beaker, filter the response and was! h off the residue. Do this with the funnel on a stand so no residue leeks into the solution. 6. Boil the remaining Copper sulphate solution until about 50% of the solution has evaporated. 7. Leave to cool institutionalise and crystallize. 8. Dry the crystals between fresh filter papers and when full dry weigh the results. Result/Data collection: Amount... If you hope to get a full essay, order it on our website: OrderCustomPaper.com
