Experiment

Experiment: - Determining superman concentration Aim:- The resolve of this experiment is to determine the concentration of two acrids, hydrochloric acid HCl, and Ethanoic acid, by thermometric titration, and having done that, to calculate the enthalpy change of neutralization. set in motion:- both hydrochloric acid and ethanoic acid were titrated. In turn with a standardized settlement of sodium hydrated oxide and temperature of the mixtures was recorded during the go into of titration. In each case a plot of temperature against measurement will enable as to determine the maximum temperature rise. From which we careful the concentration of acid and the enthalpy change of neutralization. Requirements:- Safety nerveglasses pipette 50.0cm Pipette makeweight Expanded polystyrene shape sodium hydrated oxide solution 1Mol Thermometer Burette, 50.0cm try funnel, small hydrochloric acid Ethanoic acid Risk Assessment :- as usual in some(preno minal) lab experiment we dressed on safety coats, and the operate was done smoothly to avoid any breakage and distress. sodium hydroxide is very corrosive therefore we used, the pipette filler supplied and safety eyeglasses. Hydrochloric and ethanoic acids can cause serious permanent change to skin so extra care was given. Contact with the eye can cause serious long-term damage.

Hence spectacles were on all the time. Procedure:- Titration of hydrochloric acid with standardizes sodium hydroxide solution 1. 50 cm of NaOH solution was transferred into the polystyrene cup by victimization pipette. Few minute s was give to stand. 2. The temperature was! recorded. 3. 5cm of HCl solution was added to the cup by using burette. 4. The mixture was stir, using the thermometer, and the result was recorded. 5. 5cm portions of hydrochloric solution were added successively, it was stirred and temperature was recorded. 6. The results were recorded in the table below, after the asset of 50cm of acid Titration of Ethanoic acid with standardizes sodium hydroxide...If you want to get a full essay, assign it on our website: BestEssayCheap.com
