Investigation Completion and Analysis Essay

E vaporizationation is a serve well where semiliquid is converted to vapor with the economic consumption of separating it from a change state substantialness or from a liquid that is higher in boiling head word in experiments or investigations on how to separate dis dissoluble solid in liquids (Holland, 2005). Evaporation proficiency was elect for the experiment because it is easy and simple to coif compared to other methods of insulation much(prenominal)(prenominal)(prenominal) as distillation.2. DistillationDistillation is an investigative proficiency used in separation of mixtures ground on conditional and differences required to interchange the components phases of the mixture. It push aside be employ in a mixture of liquids, and the mixture of soluble solutes and firmnesss like in this experiment. During the distillation mold, the piss is heated into the gas phase of the vapor leaving the salts deposits, t therefrom condenses back into liquid form that is then collected. The carry out is then repeated again to improve the peeing supply system system supply purity (Porteous, 2010). This method was obtained because saturated water supply back tooth be obtained3. CrystallizationThis technique is a play of solid crystals organisation from a source. This technique is a technique of separating solids and liquids in which transfer of solute from a base to a solid crystalline which pure occurs (Jones, 2002). This method was chosen because pure solutes can be obtained.Modifications made, and justification for the changes1. In drying up, I employ some heat from flames to the containers keeping solution of water and salt. I utilise the heat to increase the rate of evaporation instead of leaving it open in the air and under the sunshine that is slack.2. I used ice in the capacitor to condense maximum amount of vapor. Moreover, I re-distilled the condensed water to get maximum dissolved salts again.3. In crystallisation, I left the crystallisation dish up to proceed slowly unruffled instead of fast cooling. This was to prevent impurities from acquiring attached to the salts and also to get big crystals.Ways to moderate the accuracyTo control accuracy, I ensured that the same amount of solvent and solution was used in the iii experiments. Moreover, an equal amount of time was applied on all the experiments to get dead-on(prenominal) results. Lastly, I ensured that the salts and the water had no impurities that could relate their boiling points.Ways to ensure dependablenessReliability in the techniques was determined by the experiments producing consistent results. To ensure reliability, I started with the evaporation method which the results were salt and water, distillation and crystallization also produced consistent results of salt and water.Ways to ensure validityValidity indicates the extent to which the applied technique in the separation assist separated the components it was intended to separa te. To ensure the validity, I ensured that salt and water which were the components of the solution that was to be separated were the end products.The process requires a lot of heat vim which capacity be expensive. However, solar heat is slow and evaporates small quantities of the solution. The method is suitable in situations where salt is the only product needed. However, array of water vapor is difficultDistillationThe distillation process desalinate water removes dangerous strenuous metals like mercury, arsenic and lead, and the soluble salts that change the water such as magnesium, calcium and phosphorous. Therefore, it is preferable for distillation of drinking water. However, this process is ineffective in separation of soluble salts that has lower boiling points than water such as synthetic chemicals, chlorine solutions, herbicides and pesticides (Porteous, 2010). Moreover, it requires banging source of heat which is costly. Lastly, the distillation process strips wate r its natural trace elements thusly the hydrogen composition in water increases and makes water acidic (Porteous, 2010).CrystallizationThe process is complex compared to the evaporation method. It is also discordant where water is to be collected as an end product. However, it is advantageous since pure salts can be obtained for usage (Jones, 2002).b) Suggestions of possible improvements ersatz sources of heat could be used such as the use of solar energy to reduce high costs incurred in the evaporation and distillation process. Despite the particular that solar energy cannot produce a high amount of energy needed to heat the large amount of the solution for a longer duration of time, it is the dress hat cost-wise.Given that some dissolved salts get to lower boiling points than the water hence difficult to separate them from water, the boiling point of water can be let down by lowering the gas pull above the liquid.The distillation process strips water its natural trace elemen ts, hence making water to be acidic cod to increased proportion of hydrogen. To avoid water being acidic, beneficial salts can be added into the water for human consumption such as calcium that is good in formation of bones.ReferencesHolland, C. D. (2005).
