    The Recrystallization of Benzoic Acid through solubility and filtration. Summary: An ideal solvent of 95% Ethanol was determined from the given solvents of water, 95% ethanol and hexane. Once the ideal solvent was determined a recovery of 27% or 0.54 grams of Benzoic Acid from 2.0 grams of crude Benzoic Acid mix using the 95% ethanol. The product was a white crystalline solid that produced a melting point range of 116-120 C compared to the actual range of 121-123 C meaning that a small amount of

    Quantification of Caffeine and Benzoic Acid in Mountain Dew Using HPLC Jordan Carey 1 UNF Dr, Jacksonville Fl 32246 Abstract The regulation of contents in beverages is important for the health and safety of the public. The chemicals caffeine and benzoic acid are common additives to beverages for the stimulation effect and as a preservative, respectively. To simultaneously determine the amount of each of these chemicals, a method combining UV/Visible spectroscopy and reversed-phase high performance

    mixture of Benzoic acid, Benzocaine, and Fluorenone. Because the ratio is 1:1:1, that means all of the components are equally weighted in the total weight of the mixture. Since the starting weight of the 1:1:1 heterogeneous mixture was 0.618 g, you can assume that the 0.618 g is made up of the three components each weighing 0.206 g. This came from dividing the starting weight by 3, since there are three components. As shown in the percent recovery calculations above the percent recovery of benzoic acid

  • Combustion Of Benzoic Acid Lab Report

    The purpose of this experiment was to determine the resonance energy of benzene. 0.512g of benzoic acid was used to do a combustion reaction which was completed during a period of 10 minutes as shown in figure 1 below which was created using table 1 below. The change in temperature during this combustion reaction was found to be 1.45K. Table 1: Change in temperature during the combustion of benzoic acid. Time (min) Temp. ( ̊C) Time (min) Temp.

    inorganic species. The specific substance being tested first, is the organic compound benzoic acid. The objective of the first set trials is to acquire data which can be used to determine the best solvent for the recrystallization of benzoic acid. Next, potassium permanganate, an inorganic salt, will be dissolved in a variety of organic solvents, with the aid of phase transfer agents. First, the solubility of benzoic acid was tested. Four solvents, water, ethanol, acetone and hexanes, were used in an

  • Extraction of Benzoic Acid Essay

    is to practice common organic laboratory techniques inside the lab to get one oriented to the basic methods of procedure that can be used for later experiments. This experiment involves the separation of benzoic acid from a more crude form, consisting of benzoic acid, methyl orange, a common acid/base indicator, and cellulose, a natural polymer of glucose (Huston, and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process of separating

  • The Separation Process Of Naphthalene And Benzoic Acid

    881 Words  | 4 Pages

    Naphthalene and benzoic acid are two compounds studied in this experiment. Sodium benzoate is also an important substance involved in the separation process. The separation technique used to extract the different compounds of a heterogeneous mixture is based on solubility and density. Regarding naphthalene and benzoic acid, their chemical properties differ from one another (Separation 1). The detailed separation process of naphthalene and benzoic acid, found in a mixture, follows. First of, when
