Courtney NikulkaLab TitrationPurpose: The purpose of this lab is to determine the concentration of sodium hydroxide using titration. Data Table:TrialVolume of acid used Volume of 0.1M NaOH usedNumber of moles of NaOHNumber of moles of acid presentConcentration of hydrochloric acid mol/LTrial 1 25 mL or 0.025 L25.4 cm3 or 25.4 mL or 0.0254 L 0.00254 mol0.00254 mol0.102 mol/LSample Equation:Concentration = amount of solute∈molvolumeMole = 0.00254 moles (same as NaOH because of the 1:1 ratio)Volume of HCl = 25 / 1000 = 0.025 dm3Concentration = 0.002540.025= 0.102 mol/dm3= 0.102 mol/LDiscussion:1.One source of error is that the drops may not be small enough to get a precise measurement. Using a dropper is also not the most precise way to measure the volume of NaOH at the end either. Another source of error would be that the human eye could miss the liquid turning slightly pink. Each person can perceive colour differently leading
