preparation of aspirin and oil of wintergreen | Introduction Organic compounds are those which contain carbon as well as a select other elements. An organic acid however‚ is an organic compound which contains acidic properties. An ester is an example of being a derivative of these organic acids. Esters can be prepared by the reaction of carboxylic acids and alcohols‚ with an inorganic acid used as a catalyst which is dubbed esterification. With o-hydrobenzoic acid‚ or salicylic

RUNNING HEAD: Synthesis of Banana Oil Abstract A reflux apparatus was assembled with a water-cooled condenser and a drying tube. Isopentyl alcohol‚ glacial acid sulfuric acid is added to a 25 milliliter round bottom flask and attached to the reflux apparatus. The mixture was boiled‚ the extracted first using water followed by aqueous sodium bicarbonate. The mixture was dried using anhydrous granular sodium sulfate. After dried‚ the sample was placed in a distillation apparatus and heated. This

Milikan Oil Drop Experiment Objective To experimentally determine the quantum nature of charge by using the equipment especially designed for this experiment. Theory A spherical drop of oil‚ falling through a viscous medium like air‚ will quickly reach a constant velocity. When it reaches this equilibrium state‚ the viscous force is balanced by other forces acting on the drop‚ such as gravity‚ buoyant forces from the air‚ electrical forces‚ etc. In this experiment an electrical force of varying

OBJECTIVES To demonstrate the effects that a bypass capacitor has on amplifier voltage gain (Av). To demonstrate the ac operation of the common-emitter (CE) amplifier. INTRODUCTION A common emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies‚ typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input‚ the collector is the output‚ and the emitter is common to both. The input signal to a

Title: Liquids and Solids Purpose: The experiment will help determine two important physical properties‚ boiling and melting point‚ of liquids and solids. Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel

On what I have seen‚ the first experiment showed chemical reaction to be more specific‚ combustion. In the experiment the Potassium permanganate (KmnO4) was used as the oxidant‚ and obviously oil as the fuel. As the two were mixed they needed to release energy in form of heat‚ that’s where combustion occurs. I learn that Combustion is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of

The Philippine banana industry is one of the top agricultural export earners. The increase in demand worldwide has resulted to greater expansion of area planted to banana. As a tropical country‚ Philippines grows an abundant varirety of fruit crops primarily for local consumption and export market. Banana is considered as the most important fruit crop in the country in terms of volume production and export earnings. Philippines ranks second to Ecuador as the top banana-exporting country in the world

You’ll never look at a banana the same way again after discovering the many health benefits and reasons to add them to your diet. Bananas combat depression‚ make you smarter‚ cure hangovers‚ relieve morning sickness‚ protect against kidney cancer‚ diabetes‚ osteoporosis and blindness. They can cure the itch of a mosquito bite and put a great shine on your shoes. If you think bananas are just for monkeys‚ think again. 1. Bananas help overcome depression due high levels of tryptophan‚ which
