    Thermochemistry Lab #2 -   Heat of Reaction - Hess's Law          Return The foundation of the study of thermochemistry was laid by the chemist Germain Hess, who investigated heat in chemical reactions during the last century. One statement of the law that bears Hess's name says: The enthalpy change for any reaction depends on the products and reactants and is independent of the pathway or the number of steps between the reactant and product. In this experiment, you will measure and compare...

  • Standardization of Sodium Hydroxide

    12-STANDARDIZATION OF SODIUM HYDROXIDE Standard solutions for titrations are especially pure mixtures with exactly known concentrations. Primary standards are very pure solids. They have the advantage that they can be weighed (the analytical balance is normally the most accurate instrument in the laboratory) and they are stable under laboratory conditions. In this experiment, the primary standard is oxalic acid dihydrate, H2C2O4 ( 2H2O. It will be used to standardize a solution of sodium hydroxide. ...

    Reacting Acids and Bases Lab Report Introduction Every liquid, except for distilled water, has either acidic or basic traits. An acid is sour tasting, and gives a sharp stinging pain in a cut or wound, and bases taste bitter, and feel slippery. A pH scale is used to determine what traits a liquid has; acidic or basic. The scale focuses on OH- (hydroxide ions) and H+ (hydrogen ions). The scale goes from 0 to 14. 7 is distilled water, as it is directly in the middle; neither acidic or basic. Acids...

    Abstract A buffer is a solution that resists changes in pH when H+, OH-, or H20 is added. By using standard lab equipment, a lab pro diagnostic tool, and acidic and basic solutions, the pH can be found. By recording the pH while adding a base or an acid gradually to a buffer solution you can find the capacity of each buffer to resist drastic changes in pH. The best buffers will keep a solution from becoming either too acidic or basic with the addition of a strong base or acid. Introduction The...

    acid is added in excess to the calcium carbonate and the excess titrated against standard sodium hydroxide. This kind of titration is termed back titration. In this procedure, the analyte is consumed using excess titrant and the end point is then determined by titrating the excess with a second titrant. Thus, two titrants are used, and the exact concentration of each is needed for the calculation. Sodium hydroxide is the second titrant in this experiment. HNO3 + NaOH NaNO3 + H2O ...

  • Saponification: Sodium Hydroxide and Soap

    liquid soaps, shampoos and soft soaps because it produces soap of soft consistency and higher solubility in water. Other raw materials: * Builders These are essentially used to build up soaps. Examples of alkali builders are sodium carbonate, sodium silicate and sodium sulfate. * Fillers Fillers increase the bulk of soap by adding weight, thus reducing the production cost. Clay, kaolin, talc, starch, common salt, chalk and magnesium carbonate are the most commonly used fillers in soap...

  • Titration: Acid and Solution

    been watered down, to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH), which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5, although...

    volumes of weak acid and weak bases of specified concentration were prepared and titrated against strong acid or strong base solutions with pH readings taken at frequent intervals to determine pH ranges over which the systems are most effective. The Henderson-Hasselbalch equation was used to calculate an appropriate ratio of acid:base volumes in order to prepare a buffer solution with a given pH value. The main results conveyed the optimum pH range for each buffer system, where significant changes of...

  • Salicylic Acid preparation Lab 1

    Experiment #1: Synthesis of Salicylic Acid From Wintergreen Oil By: Asad Razzaq TA: Date: 18/01/2015 222/Lab Section 8 Introduction Salicylic acid, used in production of substances used worldwide such as commonly used analgesic drug aspirin(cite), can be obtained from natural resources such as wintergreen oil or can be synthesized. Through a series of chemical reactions with cheap raw materials beginning with beginning with methyl salicylate and, it is a cheaper and more...

    of flask so that any solid material drops to the bottom. After the solution was mixed for a few minutes, 50% sodium hydroxide (0.30 mL, 7.5mmol) was also added dropwise and was allowed to stir vigorously for about another 30 minutes. The stir plate is then slowed down to a gentle spin. Water (3mL, 0.16mmol) was then added to the solution and allowed to spin for a few more minutes, and the solution has formed a bilayer. The solution was then poured into a separatory funnel along with additional water...
