    The type of measurement that I was able to record with the most number of significant figures was the mass. To measure this, I used an electric scale which showed up the the 0.001 place, and when objects were placed on it, it showed at least 4 significant figures. The exactness of these measurements mean that they were precise. The substance with the highest deviation is both metal B and metal D, both with a deviation of 1. The substance with the lowest deviation is solution C. (Data tables of Deviation

    VOLUMETRIC ANALYSIS 1. In volumetric analysis, the volume of a reagent needed to react with analyte is measured. 2. In a titration, increments of the reagent solution -the titrant-are added to the analyte until their reaction is complete. 3. The most common titrations are based on: - acid-base - oxidation-reduction - complex formation and - precipitation reactions 1. Methods of determining when the analyte has been consumed include: - detecting a sudden change in

    Conclusion: The purpose of this experiment was to determine the concentration of an unknown acid by performing volumetric analysis via a titration procedure (Beran, 2014). The acid that was used as the analyte was unknown A, an originally clear solution of hydrochloric acid that turned hot pink after having added approximately 14.50 and 14.40 milliliters of sodium hydroxide, for trials 1 and 2 respectively. The molarity calculated for this acid was found to be 0.86 M, but this value is not accurate

    Calibrating A Volumetric Pipette Ryane Washington Quantitative Analysis Lab INTRODUCTION This experiment was conducted to learn the relationship of 3 different types of pipettes and how to be accurate at measuring volumes of substances very accurately in quantitative analysis lab work. The accuracy of the measurement is the degree of closeness of measurements of a quantity’s actual volumes and the precision is the degree to which that are repeated measurements that are not changed show the

    Chemistry Practical Investigation-Volumetric Analysis Discussion: Based on the data obtained, the precision of obtaining the data is high. This is because the data shows closeness between one another. It shows the reproducibility of a set of measured quantity. The data obtained showed three concordant titres where the titre volumes differ by less than 0.1mL from the highest to the lowest. The variability of a measurement cannot be determined from a single measurement, therefore multiple measurements

    Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Manalo, Ma. Cristina Joyce B. Department of Chemical Engineering, Faculty of Engineering University of Santo Tomas Espana, Manila A. Abstract Crude sodium bicarbonate or commonly known as soda ash may contain amounts of impurities like chlorides and hydroxides. The total acid neutralizing capacity of a soda ash sample, its alkalinity value, was stated in terms of mass of sodium carbonate. In doing so, any

    negligible height change, and steady state, Bernoulli’s equation can be simplified to show the correlation between the volumetric flow rate and the pressure drop. The equation for both meters is as follows: w=Qρ=CYA22gc(p1-p2)ρ1-β4 (1) 1 where A2 is the cross-sectional area of the throat, C is the coefficient of discharge (dimensionless), gc is the dimensional constant, Q is the volumetric rate of discharge measured at upstream pressure and temperature, w is the weight rate of discharge, p1 and p2 are

    The paper reports water and gas flow measurements through carbon nanotubes with diameters of less than 2 nanometers. The measurement of water flow indicated that the values exceeded those predicted by hydrodynamics models by several orders of magnitude. The water flow rates were similar to those predicted from molecular dynamics (MD) simulations. The measurement of gas flow revealed that the predictions given by the Knudsen Diffusion model, commonly employed for systems in which the pore diameter
