Accurately determining the amount of an analyte (unknown), in terms of concentration, is largely dependent on the quality (accuracy) to which standards are known and the quality of the tools (sensitivity and calibration accuracy) used to make the determination. solution that was made was then used as the base in both titrations. To calculate the concentration of ethanoic acid CH3COOH in vinegar using stoichiometric equations, ( Yamaha brand ), Since the calculations yielded a 20% error, this shows that experimental error occurred during the experiment. This is done through adding a base to an acid or and acid to a base. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. Factors that could have affected the results included improper reading of the meniscus for volume of NaOH, not allowing the NaOH to fully drip into the buret after removing the funnel, adding too much acetic acid after the indicator flashed pink to get an inaccurate equivalence point, and not allowing the solution in the beaker to mix thoroughly to get an accurate reading from the pH. This was likely due to human error - namely through the inefficient cleaning of the pH probe with distilled water (resulting in inaccuracies in pH readings) and mildly varying amounts of HCl dropped per test (thus making our data points for HCl used disproportional with the given pH at that moment). Cross), Biological Science (Freeman Scott; Quillin Kim; Allison Lizabeth), Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B.
