Courtney Nikulka Lab Titration Purpose: The purpose of this lab is to determine the concentration of sodium hydroxide using titration. Data Table: Trial Volume of acid used Volume of 0.1M NaOH used Number of moles of NaOH Number of moles of acid present Concentration of hydrochloric acid mol/L Trial 1 25 mL or 0.025 L 25.4 cm 3 or 25.4 mL or 0.0254 L 0.00254 mol 0.00254 mol 0.102 mol/L Sample Equation: Concentration = amount of solute mol volume Mole = 0.00254 moles (same as NaOH because of the 1:1 ratio) Volume of HCl = 25 / 1000 = 0.025 dm 3 Concentration = 0.00254 0.025 = 0.102 mol/dm 3 = 0.102 mol/L Discussion: 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
