    EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

    transported to the liver‚ where it undergoes conjugation and excretion. Upon its separation from albumin on hepatocyte membrane‚ bilirubin binds to specific carriers and is intracellularly transferred to the site where it conjugates with glucuronic acid to form bilirubin diglucuronide and bilirubin monoglucuronide. During this process‚ the insoluble form of bilirubin is converted into its soluble form‚ known as conjugated or bound bilirubin. Upon conjugation‚ the bilirubin from hepatocytes is excreted

    Voltmeter A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. The first digital voltmeter was invented and produced by Andrew Kay of Non-Linear Systems (and later founder of Kaypro) in 1954. RHEOSTAT A rheostat is a device which is used

Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different
