Lloyd Term 2‚ 2014 Lauric Acid Experiment Teacher: Mr Oliver Contents 1.0 Introduction Elements and the compounds can exist in distinctive physical states. Liquid‚ solid‚ gas and plasma. Every element and compound has a distinctive melting and boiling point. When a substance reaches its melting and boiling point it will change phase. For example the molecules in a solid being heated gain energy and eventually are able to not only vibrate but

final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore

Preparation Of Triphenylmethanol Objectives 1. To study the preparation of triphenylmethanol using through Gridnard reaction 2. To study the operations of anhydrous reaction‚ water vapor distillation. Principles Alcohol is widely used in organic chemistry‚ not only as solute but also as intermediate to synthesize halide‚ alkene‚ ether‚ aldehyde and ketone etc. In laboratory‚ an important method of synthesizing alcohol is though the addition reaction of Gridnard reagent and carbonyl compound‚ whereas

Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance

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 are

In order to find the Vitamin C content you will need to use a process called titration which‚ according to the Columbia Electronic Encyclopedia‚ is when you add a chemicals to a liquid in order to create a reaction which can determine the content of a substance inside the liquid. This is how you will find the Vitamin C content of different juices. Iodine will be added to the juice‚ which will create a reaction that can help determine the Vitamin C content. To start‚ pour 30 milliliters (mL) of Lugol’s

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

acetic acid present in commercial vinegar and the weight-to-volume percent of ammonia present in window cleaners. Acid-base titrations can be conducted using the above samples against standardized aqueous NaOH and standardized aqueous HCl solutions respectively. 2. Introduction: Acetic acid‚ commonly known as ethanoic acid CH3COOH‚ is found in commercial vinegar. It is a weak organic acid that gives vinegar its characteristic pungent smell‚ sour taste and slight acidity. Being an acid‚ vinegar
