    Purpose The purpose of this lab is to find the boiling point of the liquid and find the melting point of the solid. Procedure Boiling point: To find the boiling point of Isopropyl Alcohol I put about 1 mL of it in the test tube. Then I attached the thermometer to the test tube with a rubber band(make sure the thermometer bulb is lined up with the end of the test tube). After that I made a water bath with a beaker and put in the test tube with the thermometer. I then used a burner and a burner stand

    1.0 Aim The purpose of this experiment is to use Volumetric Analysis to determine the concentration of acetic acid in white vinegar. 2.0 Theory The concentration is a measurement of relative amounts of solute and solvent. There are many diverse ways of expressing concentration but the most accepted and widely used is molar concentration and regularly referred to as molarity which is defined in mole‚ the amount of solute dissolved in one litre of solution. [pic] In this experiment there

    Acetylsalicylic acid is the active pharmaceutical ingredient in aspirin and can be synthesized by the esterification reaction of salicylic acid and acetic anhydride in the presence of an acid catalyst. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. When heating the salicylic acid mixture in the warm water bath‚ the mixture should be removed from the bath within 8 minutes‚ to reduce the chance of the acetylsalicylic acid decomposing

    Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

    Melting Permafrost’s Negative Contribution to Global Warming [pic] Global Warming is a problem that impacts the entire planet. The average temperature of our planet has risen about 0.5°C in the last 100 years. According to field biologist Wolter in 2008‚ the melting of permafrost in the colder regions of the world is mostly responsible for global warming; causing the world’s climate to be at risk. (Wolter‚ 2008) “Permafrost is any rock or soil that remains frozen constantly

    BEHAVIOUR OF AMINO ACIDS IN SOLUTION Abstract In this practical the acid-base behaviour of amino acids was assessed. Amino acids are amphoteric. They have the basic (amine) and the acidic (carboxylic) functional groups. These show the same type of equilibrium reactions that all weak acids and bases undergo‚ and the relative amount of each can be altered by adjusting the pH of the solution. For this practical glycine was used as a model to show this unique nature of amino acids. A series of
