Chemistry 11:  We started with a lesson on Ester Formation, then made and completed a homemade worksheet with 5 different reactions.  Esters make many flavours in fruits:  check out this graphic of different esters and their acid & alcohol components.   Lab 16A was prepared for Monday, then time was given for the Practice Final and the Organic Practice Test.  In the second half we took notes on the conductivity in solutions.  We read sections 9.1 and 9.2, then did Unit 9 # 6-8.
