How Sweet It Is! Determining Percent Sugar ANONYMOUS Chemistry 6th Due: 3/21/12 Introduction Background Information Sugar is an import compound that is used by all complex living organisms. There are many types of sugar including glucose, fructose, and lactose. However, the type of sugar that is tested for in this lab is the common sugar used while cooking. This sugar is called sucrose. Sucrose is a combination of glucose and fructose. Glucose and fructose combine to make sucrose in a dehydration synthesis reaction. Sugar, or sucrose, is used as an energy source by humans. Sucrose is used to sweeten foods, and provide short term energy. In sodas such as the orange soda and clear soda used during this lab, the sugar is used to sweeten the drink. Density can be used in order to find the sugar concentration in a particular solution. Density is known as the amount of mass that will fit into a certain volume. For this lab, the density of water will be 1 gram/cubic centimeter. The mass of a certain substance is the amount of matter it contains. The volume of a certain substance is the amount of space the matter takes up. The density of a solution will depend on the solute, and the concentration of the solution. The concentration of a solution is the amount of solute that is dissolved into each unit of solvent. In this lab, water (H2O) will be the solvent and sugar/sucrose (C12H22O11). When the density of the solute is greater than the density of the solvent, the density is directly proportional to the concentration of the solute. The relative density of the solute to the solvent can be observed by placing some solute into the solvent without mixing. If the solute floats, then the density of the solvent is greater than the density of the solute. If the solute sinks, then the density of the solute is greater than the density of the solvent. In this lab, the density
