Solubility

1. Provide a general discussion of the solubility/miscibility behavior observed in procedure A-D. For part A of the procedure we worked with the solubility of solid compounds in various solvents. The three solid compounds that were worked with during this procedure were benzophenone, malonic acid, and biphenyl. These three solids were then mixed with water (highly polar), methyl alcohol (intermediately polar), and hexanes (nonpolar). When benzophenone is mixed with water the results turned out to

At what temperature is more KCl able to dissolve: 40°C or 90°C? 90 C since with the KCl we found that the higher the temperature the more likely the substance is to have greater solubility. How is temperature related to the solubility of a salt? Explain your answer. Solubility increases with temperature because the increase in kinetic energy allows the solvent molecules to break apart the solute molecules that are held together by intermolecular attractions. Which salt is more soluble, KCl

Virtual Solubility Lab This lab was performed to test how fast a solute would dissolve in a solvent. My hypothesis was that the higher the temperature of the water is, the faster it will dissolve. There were many materials needed to execute this experiment. We needed a Hotplate, graduated cylinders, beakers, water,and goggles When performing this lab, it was necessary to be precise. There were three different measuring spoons to use. There was 25 grams, 10 grams, and 1 gram. I put as much of the

Solubility, which influences gases in solution, is dependent on temperature. When using water, increasing the temperature decreases the solubility of gases. This is because whenever the temperature of a gas increases, the kinetic energy of that gas increases as well. This causes intermolecular bonds to break and allows the gas molecules to escape the liquid. The decreased temperature of the liquid causes it to be more oxygen rich. Liquid breathing is when an organism breathes an oxygen-liquid as

a better understanding of the thermodynamic properties and solubility constant (Ksp), and those properties relation to ∆G˚. Thermodynamics is the study of hat energy and other values of work, temperature, and energy regarding the process of a chemical reaction. A goal of this experiment is to be able to measure the solubility of KNO3 as a function of temperature, and analyze this function graphically. This graph is based off of solubility and temperature change, or more specifically the

I. Purpose: How does temperature affect the solubility of salt in water? II. Hypothesis: If temperature affect the solubility of salt in water, then when tested the warm water will have a much greater solubility. III. Materials: two-500 ml beaker, a source for warm/hot water and room temperature water, stirring rods, a container full of salt, cup for the salt, a scale, heat pads, a thermometer, safety googles and aprons. IV. Procedure: First fill one baker with room temperature water and another

Procedure: 1. A beaker was filled with 100 ml of room temperature of water

Separation of the Components of a Mixture General Chemistry 1 (Chem 101), ISP SCUHS Report 2 January 26, 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques, we examined our solutions such as SiO2 (sand), NH4Cl (ammonium chloride), and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions, we made calculations

Abstract: Therapeutic response of a drug depends upon the bioavailability which in turn depends upon the solubility and dissolution rate of drug. A solubility problem is a major challenge for the pharmaceutical industry with developments of new pharmaceutical products. There are various techniques but liquisolid compact is a new and promising method that can change the dissolution rate of water insoluble drugs. According to the concept of liquisolid systems water-insoluble drugs dissolved in suitable
