As we all know, tomorrow we are doing a lab regarding titration, a concept that is fairly new to us. For review about this concept, refer to your notes or Maria's previous blog post. I am going to summarize tomorrow's lab in order to ensure our procedure's accuracy.
Basically, the goal of the lab tomorrow is to use your acid (vinegar or lemon juice) and use the titration method to find an unknown molarity, which will be the molarity of your acid. This experiment requires extreme detail because we are trying to find the equivalence point (or endpoint), which will be determined by the color change of our universal indicator. My one suggestion: Add each drop of NaOH very slowly in order to prevent you from passing the equivalence point and potentially having to start the entire experiment over again.
I hope this brief explanation cleared up the purpose of tomorrow's lab! Good luck to everyone!
Here is a picture of the color change that we are expected to see tomorrow.
