Volumetric analysis (titrations)
Before going any further, this is probably a good point to revise good lab practices.
Also, it is expected to you are using significant figures and units correctly in all of your calculations. Perhaps revise this to make sure.

Titrations
The practical component of this course requires you to complete several titrations. You will have the opportunity to practice this technique in the lab prior to completing a summative investigation. It is important that you are well prepared for these sessions. Please complete the assigned reading from the Essentials workbook and Discovering Chemistry paying particular attention to the sections relating to titration technique and procedure. You should also watch the videos below.
