SQ14

I was just reminded of an incident which happened in my inorganic chem lab session. We were doing titration, and I was about to reach my endpoint, adding the solution drop by drop. Then one of the teacher assistants (TA) tapped my shoulder and said, "I show you the correct way of holding the burette tip." Then she started spraying the damn solution into the conical flask, and the whole thing turned dark pink. I was so shocked, so disbelieved, so pissed, that I was totally speechless! I spent so much time and effort doing the titration and she totally ruined it!
Lesson learnt: Never ever let anyone disturb you when you are doing titration or any other experiments.
