Question

As part of the aspirin synthesis lab the orgo students also had to perform the following calculation to demonstrate their knowledge. Are you able to help them work this out?

Saponification is a process in which soap is produced from the chemical reaction between animal fat (triglycerides) and a strong base such as KOH.

An example of such balanced chemical reaction is shown here:

C51H98O+   3KOH   → C3H5(OH)  +   3C16H31O2K

                          (Triglyceride)                                                      (Soap)

if during the saponification reaction 231.5 g of C51H98O is mixed with 231.5 g of KOH and 160 g of soap is produced.

  1. Calculate the theoretical yield of soap C16H31O2K and indicate who is the limiting reactant. (Provide your answer to 2 decimal places)
  2. Calculate the percent yield for this reaction (Provide your answer to 1 decimal place)

 

*Show ALL steps and mathematical equations involved in your calculations to help the orgo students. Remember to label all steps clearly and use all appropriate units.
