and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing with HCl and heating. The dark black solution is filtered through a gravity filtration system allowing the slightly pink liquid to pass through the fluted filter paper. This process can be slow to drain leave only the remaining insoluble impurities in the filter. Once the pure sample is collected the crystallization process begins

that are used in our day to day life‚ such as filtration‚ Centrifuging‚ Decanting‚ fractional distillation and sieving. Each of these methods has their own specific uses in our daily lives which make our chores much easier to carry out. Filtration is one of the most commonly used separation technique in a household. This method uses a funnel outlined by a sieve called the filter to separate the solid “residue” from the liquid “filtrate.” Filtration is useful because both phases can be obtained

thoracic legs. The particles are then transferred to their mouth groove to be ingested. D. magna typically feed on planktonic algae (Ebert‚ 2005). The following experiment uses algae to test what affects the feeding rate of D. magna. The rate of filtration is dependent on multiple factors including temperature‚ food density‚ body size‚ and water pH.

During the evaporation of water while using the Bunsen burner‚ the flask might crack or explode – this can be avoided by not heating the flask over a prolonged period of time‚ and not heating it too intensely. Some of the sand may be lost during the filtration – this can be avoided by carefully filtering the mixture‚ and making sure that all of the sand has been washed off from the beaker‚ and the rubber policeman. Some of the salt may be lost if the salt doesn’t dissolve completely or if some of the
