Concentration Of Vinegar
Abstract:
This experiment was designed to identify whether the concentration of the given vinegar had a concentration of 5.0 % acetic acid. By calculating the concentration it can be identified that the concentration acetic acid was more, accurate or less then the advertise and specified amount. It is important that the vinegar concentration be accurate because issues may arise, if they percentage is off, such as health or government. Continuous testing is done on many products to ensure the safety of the consumers. This experiment outlines these tests. This experiment uses titration to identify the unknown concentration of the acetic acid in the vinegar solution (Nelson Chemistry 11, 2002). After the process of titrating 3 solution until a pink colour was constant in the solution the amounts of NaOH (aq) were recorded, this information was used in a stochiometry calculation to identify the unknown concentration.
Introduction:
This experiment is designed to calculate the percentage of acetic acid in cafeteria vinegar. By law consumer products are required to have a minimum quantity of active ingredient listed on the products label (Nelson Chemistry 11, 2002). This experiment compares the percentage of vinegar from the consumers vinegar to the concentration calculated by this experiment (Nelson Chemistry 11, 2002). By calculating these two percents it would be determined if the cafeteria’s vinegar was accurate to the specified concentration. Concentration is defined by the amount of solute in a mixture, during this lab the concentration was the amount of acetic acid in the vinegar, in a given solution (W4) (Nelson Chemistry 11, 2002). A solute is a substance that is dissolved in a solvent to form a solvent, in this lab the solute was the acetic acid which was dissolved into the vinegar solution. (Nelson Chemistry 11, 2002). A solvent is a substance that the solute is dissolved into, the majority of solvents are the liquid form of the solution, in the lab the...
