Molarity's Effect On Boiling Point
The purpose of the lab is to study molarity's effect on the boiling point of a solution. The lab studies how concentration affects the chemical and physical properties of a solution. With water acting as the solvent and sugar and salt are the solute. The amount of solute added contributes to the measure of concentration. If the increase in concentration affects the boiling point than the boiling point is considered a colligative property. Colligative properties are any characteristics that can be altered through a change in concentration. The lab also used the boiling point elevation equation to take into account the ions of the solute and its

    Orgo Lab 2

    The classic example of adding salt to water leads to a phenomenon named “Boiling Point Elevation.” Impurities form chemical bonds with the solvent in which they are, holding it together in liquid form. Breaking those bonds is difficult, causing a rise in boiling point. A 5.19% error could have occurred from the temperature probe being situated too high above the side-arm. If the bulb of the temperature probe is not low enough, the temperature of the vapor that is in equilibrium with the distilling mixture will not be measured.…

    Colligative Properties & Osmotic Pressure

    Important terms to study from this lab assignment are colligative properties, membrane permeability and osmotic pressure. First, colligative properties are “those of a solution that depend solely on the number of solute particles present, not the identity of those solute particles. These properties include: vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure” (p. 17 lab manual). In this experiment freezing point depression is illustrated by comparing the freezing point of distilled water to the freezing point of distilled water mixed with a non volatile solute, salt. Another important term taken from this lab experiment is membrane permeability, which is the ability of the membrane to pass a solution through it. Membrane permeability is crucial in the effectiveness of dialysis. Lastly, osmotic pressure is “the pressure that must be applied to stop the movement of solvent through the membrane” (p. 19 lab manual). Membrane permeability and osmotic pressure is demonstrated by using the dialysis tubing when submerged in distilled water, and the raw egg when immersed in the Karo syrup.…

    Analysis of a Volatile Liquid

    The purpose of this experiment was to use various methods of analysis to determine the identity of an unknown volatile liquid. In the first part of the experiment, the molecular mass was found by using water to find the volume of a flask through calculations and this as well as the mass of the gas of the unknown liquid were put into the a manipulated version of the ideal gas equation to determine the molar mass of the liquid, which was 14.21g per mole. The next part was used to determine the density of the volatile liquid. First the volatile liquid was placed in a pyncometer and massed; water was then placed in the same (now clean and empty) pyncometer and massed. The density equation was manipulated using the data for water to solve for the mL of the capillary tube. This new information was used to find the density of the liquid, which was 1.33g/mL. The last part of the experiment was used to determine the boiling point of the volatile liquid. A test tube was placed inverted in a flask filled with the unknown liquid that was in a water bath heating. When bubbles from the test tube slowed and began to go back into the test tube, the temperature was taken and this served as a measurement of the boiling point. The average measured boiling point was 60.2°C. The measured data was inadequate to identify the liquid with. The unknown liquid was revealed to be methanol; the revealed identity could then be used to compare the data to the actual information for methanol. The molar mass was found to have a percent error of 55.6%, the density had a percent error of 68.1% and the boiling point had one of 6.95%. The measured data for the boiling point was fairly accurate, but the molar mass and the density both had very large percent error. The reasons for this will be discussed more in the discussion.…

    Collegative properties

    A colligative property of a solution or solvent varies depending on the amount of solute particles in it, though it doesn’t matter the kind of solute. The more solute the more colligative property of the solvent. Also, its boiling point changes. The more solute, the higher the boiling point. Less solute causes a lower boiling point.…

    We started setting up our experiment by measuring different molar solutions (0M, 0.25M, 0.5M, 0.75M and 1M) of sugar and putting them into separate bottles, along with one bag (12g) of yeast and 300ml of water. We then attached a tube going from the top of each bottle to separate test tubes which were entirely full of water and were placed upside down in a tub of water, stopping the tube from emptying and…

    Simple Distillation

    Distillation is one of the oldest and still most common methods for both the purification and the identification of organic liquids. It is a physical process used to separate chemicals from a mixture by the difference in how easily they vaporize. As the mixture is heated, the temperature rises until it reaches the temperature of the lowest boiling substance in the mixture, while the other components of the mixture remain in their original phase in the mixture. The resultant hot vapor passes into a condenser and is converted to the liquid, which is then collected in a receiver flask. The other components of the mixture remain in their original phase until the most volatile substance has all boiled off. Only then does the temperature of the gas phase rises again until it reaches the boiling point of a second component in the mixture, and so on. The boiling point of a substance—determined by distillation—is a useful physical property for the characterization of pure compounds. At any given temperature a liquid is in equilibrium with its vapor. This equilibrium is described by the vapor pressure of the liquid. The vapor pressure is the pressure that the molecules at the surface of the liquid exert against the external pressure, which is usually the atmospheric pressure. The vapor pressure is a very sensitive function of temperature. It does not increase linearly but in fact increases…
