Titration Lab How Much Citric Acid is in Your Soda? PURPOSE To determine the molarity (concentration) of citric acid (H3C6H5O7) in various different citrus flavored sodas. BACKGROUND PRINCIPLES Popular sodas all strive for a somewhat sour (’tart’) flavor and manufacturers utilize acids to impart this taste. While there are a vast variety of different brands of sodas on the market‚ they can be broken into two main categories: dark or clear. This differentiation is not only a simple color

Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5% and 21

good conclusion should contain all of the following parts a) You should state what experiment was performed‚ and show any necessary reaction schemes. The reaction schemes should include molecular weights and any other important physical data for the reagents and products. Ex. Cyclohexanol was oxidized to cyclohexanone using sodium dichromate in the presence of sulfuric acid. * Note: you can download a free version of a structure editor from ACD labs‚ the PC version is called chemsketch‚ the Mac version
