Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

LS Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized

Separation of a Mixture of Solids I really enjoyed this lab. After reading the introduction I started by making my own flow sheet of how I thought this lab would work. I was reminded about solubility which is defined as the amount of the solute that will dissolve in a given amount of solvent and that the extent to which a substance dissolves depends mainly upon the physical properties of the solvent and of the solute and to some extent upon the solvent’s temperature. With that being said I came

The Effects of Temperature‚ Acetylcholine‚ and Adrenaline on the Heart Rate of Daphnia magna Hieu Duong 6 April 2011 Introduction The heart is a muscular organ that constantly pumps blood throughout the human body. The continuous flow of blood creates a system for vital organs within the body to gain oxygen and nutrients. The timely delivery of oxygen to the body’s organs is very crucial. Brain cells‚ for example‚ will die within minutes if the flow of oxygen is obstructed. For the

NANCY MARASHI. | Background: During this experiment students will take a mixture and separate it into its’ pure substances. A mixture is a combination of two or more substance. These substances cannot be combined chemically but more physically. The pure substances are substances that cannot be separated any more by physical means. The students

POWER AND ITS POWERS: The Supremacy of Power Frank Chodorov‚ an American writer and libertarian once said “The State acquires power and because of its insatiable lust for power it is incapable of giving up any of it. The State never abdicates.” When I was in my high school‚ I always dreamed for Utopia‚ a perfect state wherein there is no poverty and starvation. Power is delegated in every people and there’s equality‚ justice and freedom. Utopia sometime refers for World peace‚ this may sounds

When looking at this question‚ let’s first consider what is meant by vertical separation of a firm. Vertical separation of a firm is when that firm sells the good or service they produce through an independent retailer rather than sell its product itself directly to customers which is vertical integration. So when it come to incumbent firms‚ firms in which are already well established and selling within a market would it be better off if that firm is operated as one firm that is integrated or if

Introduction: Recrystallization is used for the purification of solid compounds. The recrystallization process relies on the fact that majority of compounds are more soluble in hot solvent than in cold. The hot saturated solution containing the compound will have unwanted impurities and will be filtered out and cooled to produce the pure crystal constituents of the compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach

There have been many quarrels on the phrase “separation between church and state”. It has been a common metaphor used all around meaning that the state staying out of the church’s business and church staying out of the state’s business. This phrase has been very common that many begin to believe that it was found in our Constitution. The “wall of separation” was created by Thomas Jefferson in a letter to the Danbury Baptists in 1802 (Jefferson). It has grown to become part of the organic law of the

For many divorced and separated parents with children there will be a common answer as to why they ended up with the child custody and visitation arrangement they have. The answer being‚ "the judge decided it." In other words‚ the judge chose the parenting arrangement you have based on his/her belief of what was in your child’s best interest. Judges do not always make the child custody decision or choose the parenting plan arrangement for the parent’s. In fact‚ more often than not‚ the judge will
