    this experiment‚ recrystallization will be the method used to purify the solute sulfanilamide using ethanol as the solvent. Based on the solubility curve on the solubility versus temperature graph‚ the ideal solvent will allow the solute to be soluble at higher temperatures and insoluble at lower temperatures‚ thus making ethanol an excellent solvent for crystallizing sulfanilamide. Sulfanilamide is first dissolved in the smallest amount of ethanol just enough to dissolve the sulfanilamide

    Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid‚ the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are

    due to a temperature gradient. The microscopically diffusing and colliding objects include molecules‚ electrons‚ atoms‚ and phonons. They transfer microscopically disorganized kinetic and potential energy‚ which are jointly known as internal energy. Conduction takes place in all forms of ponderable matter‚ such as solids‚ liquids‚ gases and plasmas. By conduction‚ as well as by thermal radiation‚ heat spontaneously flows from a body at a higher temperature to a body at a lower temperature. In the

    Introduction Competition is an important interaction that occurs between living organisms that co-exist in an environment. All living organisms need certain resources in order to survive and reproduce. These resources include but are not limited to nutrients‚ food‚ water‚ and a space to live in. When these resources become limited in a shared area‚ organisms are forced to compete with each other for the resources that they need. This competition can occur among individuals belonging to the same

    end. The melting point is then determined using a melting point apparatus (Figure 1) that simultaneously heats both the sample tube and a thermometer. The temperature range over which the substance melts is recorded. Melting is said to begin when the first indication of liquid is seen. The end of the melting point range is the temperature at which all of the solid material has become a liquid. Some pure materials possess a very narrow melting range‚ perhaps as little as 0.5-1.0 °C‚

    which can also be written as ∆H=mc∆T + PV. m is the mass of what is being measured in grams. C is the heat capacity which is “the amount of heat energy required to raise the temperature of a body a specified amount” in joules per gram degree Celsius (chemistry.about.com). ∆T is the final temperature minus the initial temperature in degrees Celsius. The amount of work done by the reaction is equal to the pressure of the surroundings multiplied by the volume of the system. P is the pressure of the surrounding

The solute must have a high temperature coefficient in the solvent: it must be soluble at high temperatures and insoluble at low
