which is also known as acetylsalicylic acid. C9H8O4 is the chemical format for Asprin. The chemical structure of aspirin: Aspirin is anti-inflammatory. Aspirin is prepared by chemical synthesis from salicylic acid‚ by acetylation with acetic anhydride. The fact that it is an acid allows us to quantify the amount of aspirin in a solution. We would do this by by using an acid-base titration. Sodium hydroxide (NaOH) will be used In this experiment as the base. Preparation • Lab coats should be fully

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

Experiment 4 Synthesis of Salicylic Acid Introduction Throughout history‚ botanical extracts have been used as medicines. Approximately 30% of all medicines have a plant origin. This number increases to 60% if you consider medicines that at one time were derived from plants‚ but have been synthesized in the laboratory. Salicylic acid is a white crystalline compound that can be isolated from the bark of birch trees. Since it is a valuable substance that can be isolated from nature‚ it is called

Four bases of segmentation Geographic Collecting and analysing information according to the location of the customer or other data source. Geographic segmentation is often used in marketing‚ since companies selling products and services would like to know where their products are being sold in order to increase advertising and sales efforts there. A local shop such as a local takeaway use geographic segmentation by targeting customers within a 10 mile radius‚ they can do this by posting leaflets

The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

The Base Ball Pitch - Tom Hando The biomechanics of a movement is slightly different to the physiological principles of it. The biomechanics of a movement‚ is how the forces acting upon an object effects the way the object moves. (FIGURE 1) For example in my movement‚ the baseball pitch‚ in the wind up stage of the pitch‚ the forces acting upon the body is causing hip and knee flexion which results in the knee and hip coming into contact with the chest. Whereas the physiological principles is working

Standardize a sodium hydroxide solution by using potassium hydrogen phthalate (KHP) III. When given whether the acid is monoprotic‚ diprotic‚ or triprotic ‚ determine the molar mass of the unknown organic acid. IV. Calculate the Molarity of the Soft drink.

The five bases of power in the book are: (1) Legitimate power‚ (2) Referent power‚ (3) Expert power‚ (4) Reward power‚ and (5) Coercive power. The group member can influence others because of being elected or appointed‚ that means this person has legitimate power. Legitimate power comes from occupying a position of responsibility. People have high legitimate power should also have a high position of responsibility. For example‚ in the small group‚ the group leader or chairman should have legitimate
