We reached our goals through our experimentation. We tested the solubility of each of the starting and ending materials in water‚ HCl‚ NaOH‚ toluene‚ and acetone. We discovered that the starting materials would only dissolve in toluene. To make the soap‚ we obtained about 10 mL of vegetable oil and 10 g of lard and we placed them both in separate 250 mL beakers. While we were stirring the compounds‚ we also added 15 mL of 6 M NaOH drop by drop and 1 mL of glycerol. We then heated our solutions

Introduction For this experiment‚ we are going to determine the effect of temperature on solubility‚ to be done in a chemical by dissolving a solute in a definite amount of solution which is saturated. Specifically‚ the goal of this experiment is to prepare a saturated solution of Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring

Are our decisions always limited by the rules of society? It is a natural desire for humans to wish for freedom‚ for the ability to make their own decisions and be the master of their own destiny. However‚ is it possible to achieve this individuality despite various restrictions imposed by society? Whether “free will” exists has been the center of argument for centuries‚ but my personal opinion is that‚ the answer is negative. It is said that all ideas are children of their time. This even

“Lost and Found” “To live is to experience tragedy” is what I learned from elders coming up as a child. Whether it befalls one individually or simply those around‚ tragedies are a part of life. Sometimes tragedy happens for no apparent reason it could be in the wrong place at the wrong time or just accidental. Tragedy without any explanation is a mournful experience. For others‚ tragedy is a consequence of choices an individual makes. This brings me to my point or experience that has changed my

Rules and Regulations of Society In the 1930’s prosecution and discrimination of minority groups took place worldwide. There were specific laws put into place to restrict the rights of the black members of society in America as well as the Jewish members of the German society. Examining the harsh economic and political atmosphere during the Great Depression reveals striking similarities on Hitler’s treatment of the Jews and the laws and regulations enacted in the United States to restrict and control

CM1191 Experiment 1: Study of Solubility Equilibrium 1. Abstract The aim of this experiment is to determine the relationship between the solubility of potassium hydrogen tartrate (KHC4H4O6) and temperature. Titrate a known concentration of NaOH against a saturated solution of KHC4H4O6 at different temperatures to obtain the concentrations of KHC4H4O6‚ and hence the solubility product constant of KHC4H4O6 at various temperatures. It was found that the solubility product constant of KHC4H4O6

Use solubility of group 2 to figure out periodic trends as well as identify unknown captions Introduction The goals of this experiment were to determine periodic trends in solubility of group 2 metals. The other goal was to use our knowledge of solubility’s to identify cations present in a single unknown Xe and double unknown XXe. I have hypothesized that the solubility
Premium Chemistry Solubility Ion
Introduction: Solubility equilibrium refers to the dissolution of a compound in water. Specifically‚ the degree to which a compound is soluble (Tro‚ 739). This can be measured using the expression Ksp = [Mb+]a[Xa-]b‚ in which Ksp represents the solubility product constant (Thorne‚ 90). This constant is important because it does not change at a given temperature‚ regardless of the solution a compound is in; a smaller constant would indicate lower overall solubility. It is important to note that
