Lab Report On Titration

TITRATION OF AN ACID (A PREPARED STANDARD SOLUTION OF KH?O?C?) AGAINST A BASE (NAOH) USING PHENOLPHTHALEIN AS AN INDICATOR BY GRACE The aim of this experiment is to fake a meter solution of potassium hydrogen phthalate (KH?O?C?) and where obeisance use it to calculate the submerging of atomic pattern 11 hydroxide by titrating the dit (KH?O?C?) against the fore (NaOH). Before the whole experiment could take place, some sleeve were needed which included the following; A weighing balance, burette, pipette, a conical flask, clamp and then the setup was as to a lower place; THEORY To calculate for the moles of KH?O?C?, I utilize n (mol) =m (g)/M (gmol?? (JOHN kelvin AND SADRU DAMJI, PG 6 OF CHAPTER 1.THIRD EDITION). Whereby m= muss of the acid, M=molar crapper of the acid and n= twist of moles. Molar mass of KH?O?C? is 204.1g/mol and its mass is 1g thus=1g/204.1gmol?? n=0.0048996mol come along more, to calculate for the immersion of the acid, I utilize C(moldm?3.) =n (mol)/v (dm3) Whereby c= density, n=number of moles and v=volume employ. (JOHN common land AND SADRU DAMJI, PG 27.THIRD EDITION) Volume=0.1dm3 Concentration of acid =0.0048996mol/0.1dm3 =0.

049moldm?3 Also, to calculate for the number titre volume of the acid used, I summed up the iii consistent values from my experiment and separate it by 3(sarps series, 2009) then Average Titre volume= (19.60+19.60+19.60) 3 =19.60cm3 Al so, to calculate for the concentration of so! dium hydroxide, I used The dilution factor, C?v?=C?v? (JOHN GREEN AND SADRU DAMJI pg28, third edition) whereby C?=concentration of the acid used=0.049moldm?3 v?=volume of acid used (titre volume) =19.60cm3 C?=concentration of the base, v?=volume of the base used=10cm3 Therefore C?= (0.049*19.60)/10 C?=0.096 moldm?3 Therefore the concentration of sodium hydroxide is0.096 moldm?3 |Burette...If you want to take off up a full essay, order it on our website: OrderCustomPaper.com
