Partial Molar Volume Of A Salt In Aqueous Solution Introduction: The objective of this experiment was to calculate the partial molar volume of a salt in a aqueous solution. This was done my determining the density of binary solutions of sodium chloride and water at different known concentrations. The densities, which were determined using pycnometers, were used to calculate the end goal of the partial molar volumes of the sodium chloride and compare them against the volumes calculated for each solution
purpose of this experiment was to identify what the unknown metal was by determining what the atomic mass was. To obtain the atomic mass of the unknown metal, the number of moles of H2 gas produced from the reaction was calculated. Introduction: This lab was an application of the kinetic- molecular theory of gases. According to this theory, it stated how gaseous particles are in a constant motion where they go at random speeds as well as directions.1 According to Thomas Graham, a Scottish chemist; he
The purpose of this lab was to estimate and calculate the pH and concentration of the citric acid being used, in this case lemon juice. To measure the pH of the citric acid using the pH paper, a piece of pH paper is placed into the citric acid, changing the color of the paper. This is then compared to a chart that has average colors of paper of different pHs. To calculate the pH of the Citric Acid through titration a buret was used to dispense the base, NaOH, in to the acid H3C6H5O7. Since acids
Acid from the Plastic Syringe is injected into the Conical Flask, start immediately start the Stop Watch. Once the Stop Watch reaches 20 seconds, calculate the volume of the Hydrogen Gas. (Trail 1) Reset the Gas Syringe back to Zero; then clean, dry and wash the Conical Flask to repeat the experiment two more times in order to gain the volume of Hydrogen Gas in order to get accurate results. (Trail 2 and Trail 3) Once 3 Trails has been completed, the entire experiment will be repeated with different
