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
freezing point will decrease. Then the correlation between sugar concentration and the freezing point can be observed. Sugar and salt may appear to look similar but are quite different. Sugar is made of carbon, hydrogen and oxygen. Salt is made of sodium and chlorine. This lab will also help observe the difference of the freezing point between a sugar solution and a salt solution with the same molality. Boiling point and freezing point are
method, we use pH paper. pH is measured by inserting pH paper into the water sample and by comparing with standard pH colour chart pH of the water is noted. 2.3.2 Chloride:The Chloride contents, especially of sodium chloride or salt, are worked out for sample. The excess presence of sodium chloride indicates pollution of water due to sewage, minerals. Determination of Chloride: Silver Nitrate when added to neutral or slightly alkaline solution containing chlorides quantitatively precipitation
Experiment 10: The Chemistry of Natural Waters Kristen Vito Partners: Brandon Weiss, Matt Verne, Shrudhi Venkad Chemistry 111 Section 104 TA: Ryan O’Neill 11/11/14 Introduction Water is one of the most valuable substances on the planet. It is used in a variety of economic and industrial practices, as well as within households for everyday activities such as cooking, cleaning and more. The composition of this “everyday” water is tainted by the presence of ions, often acquired from atmospheric
Langmuir parameters Q0 and b were calculated from the slope and intercept of the linear plots of 1/Qe vs. 1/Ce as given in fig. 6-11. Fig.6. Langmuir Adsorption Isotherm, Fig.7. Langmuir Adsorption Isotherm CAC-MAC-250C CAC-MAC-300C - Fig
Literature Review History Tuberculosis, a disease caused by several species of mycobacteria that are spread from person to person through the air. It has plagued humankind for many thousands of years. TB usually attacks the lungs, but it can also attack and damage any part of the body, such as the brain, kidneys, or spine. It is a worldwide disease and in many countries is a major cause of death. After declining in incidence for a number of years, it has begun to increase in frequency, especially
