Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

cation replaces another” and in an anion replacement reaction‚ “one anion replaces another from its solution.” When magnesium and copper sulfate react‚ a single replacement reaction occurs‚ and copper and magnesium sulfate are produced (Mg + CuSO4 MgSO4 + Cu). In this example‚ magnesium is above copper in the activity series so it is able to displace copper. An example of an anion replacement reaction is the reaction of bromine and potassium iodide‚ which produces potassium bromide and iodide (Br2

Fructose is the sugar found in fruit. It is a monosaccaride‚ and is a reducing sugar because it acts as a reductant in chemical reactions. This can be seen in the Benedict’s test where the fructose in the fruit juice will reduce CuSO4 to CuO when heated. Cu 2+ → Cu + The following table indicates approximate nutritional values for each of the three fruits to be tested: Energy / kJ Water / % Sugar / mg* Sugar Concentration / mg cm3 -1 Red Grapefruit 128 90 66 0.73 Lemon 51 96 30 0.30
