  • Volumetric Analysis Lab Report Conclusion

    The two main purposes of the lab were to determine the percent by mass of acetic acid in vinegar and to determine the molar concentration of a strong acid. In both parts of the experiment a volumetric analysis was used. This is primarily the aid of volumetric glassware in order to determine specific measurements and calculations. Potassium hydrogen phthalate was used as the primary acid standard to determine the molar concentration of the sodium hydroxide solution in part one of the experiment.…

  • Brønsted-Lowry Theory Essay

    THEORY An acid is a proton (H+) donor A base is a proton (H+) acceptor EXPLANATION OF THE THEORY: Acids are proton donors and bases are proton acceptors. A hydrogen ion is the same thing as a proton since hydrogen consists of a proton and an electron. When hydrogen loses an electron all that is left is a proton. According to the Brønsted-Lowry theory of acids and bases, when an acid and a base react, a conjugate base and a conjugate acid will be produced. EXP: acid + base à conjugate acid+…

  • Solar Cells Advantages And Disadvantages

    cells There are 3 main types of commercially available cells: 3.1.1Mono crystalline Silicon PV& Polycrystalline Silicon PV The occupational health issues are associated to chemical burns and inhalation of fumes from hydro fluoric acid (HF) and other solutions of acids (e.g., HNO3) and alkalis (e.g., NaOH) used for cleaning wafers ,removing complete oxide layer, and cleaning the reactor. Performing the slicing of wafers also results in solid waste for example (e.g., small pieces of…

  • Reaction Between Sodium And Sodium Hydroxide

    is a neutralization reaction. A neutralization reaction is a chemical reaction in which an acid and a base react to form an ionic compound (a salt) and water; the resulting pH is closer to 7. The general chemical equation for a neutralization reaction is: Acid + Base Water + Ionic Compound This can also be considered as a double displacement reaction. However, since the reacts are an acid (carbonic acid) and a base (sodium hydroxide) and the products are a salt (sodium carbonate) and water…

  • Lipophilic And Hydrophilic Extraction Of Tomato Case Study

    carried out at three types of organic solvents for lipophilic fractions (ethyl acetate, hexane, 50% acetone in water) and four types of solvent for hydrophilic fractions (0.1M phosphate buffer pH7.4, acetone: water: acetic acid (70:29.5:0.5), 50% methanol in water, 7% acetic acid in 80% methanol). The amount between solid (sample) and liquid (organic solvents) was carried out at the ratios of 1:10, 1:15, 1:20 and 1:25 g:mL. The ultrasonication times were varied at six extraction time levels (10,…

  • Golf Ball Experiment

    The purpose of this lab was to identify the amount of salt needed in the water to “flink”, the point at which an object sinks or floats, the golf ball in a salt solution. Flinking occurs when the object is neither sinking or floating, it appears as if it is suspended in the middle of the solution. To flink an object, the object’s density has to have the same as the density of the solution that it is placed into. To achieve the same density of both the salt solution and golf ball, manipulation of…

  • How Does Chemistry Affect The Body

    food digestion there are chemical and physical changes occurring. One chemical change for example would be, metabolic rate which is the rate of energy that is released from macronutrients. Carbohydrates (Glucose: C6H12O6), proteins (Alanine(amino acid) CH3) , and fats (Lauric…

  • 4.2.1 Test For Milk Lab Report

    milk is mixed with sulphuric acid and iso-amyl alcohol in a special Gerber tube, permitting dissolution of the protein and release of fat. The tubes are centrifuged and the fat rising into the calibrated part of the tube is measured as a percentage of the fat content of the milk sample. Apparatus: - Butyro meter, 10.75ml pipette,amyl alcohol, stoppers, gerber centrifuge, water bath. Reagents:-Sulphuric acid, amyl alcohol. Procedure:-  Transfer 10 ml of sulphuric acid in to butyro meter .  Warm…

  • Acetone And Iodine Reaction Lab Report

    very slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable elementary steps that would otherwise not exist without its presence. In addition, a catalyst does not get used up in the reaction. In this case, hydrochloric acid reappears in the products of the…

  • Acids And Bases Essay

    A: Background Information Acids and bases are very common in today’s society, and they can be found in most households. Acids can be found as by-products of air pollution, concrete cleaner, food flavouring and is produced by the muscle. Bases are found in most cleaning products as ammonia or sodium hydroxide, and they also treat indigestion. There are many ways that acids and bases can be defined by their chemical properties. The Bronsted-Lowry definition states that acids are proton (hydrogen…
