Experiment 5, pH titration of a seeded acid with sodium carbony, materials needed. Well, this is the big one when you've all been waiting for. We're going to use a lot of our materials. You can see I've got my safety goggles on. And pH titration is the lab of labs, the experiment of experiments in general chemistry. Alright, and so going through some of the things that I have here, so I have my distilled water. As I'm going to say, I have my distilled white vinegar. I also have all of my beakers. I have my calibrated plastic pipette. The one from Experiment 2. I have my sodium carbonate solution from Experiment 4 that I made. And I know the concentration of the sodium carbonate solution. You can see I've used some of my sodium carbonate solution because I just finished running the lab and good news. It works. Now, before, as the first part of running the lab, I actually calibrated my pH probe using the two pH alpha packets that came with it. And I calibrated my pH probe as well. Using those packets, you can see I've got a bunch of labels here. Vinegar. I did my titration in my 100ml beaker. I had my sodium carbonate in my 50ml beaker. My waste beaker. My distilled water, rinsing things. And these, I did just run the experiment. And before I ran the experiment, the actual titration part, I actually had these two beakers, the 250 and the 500 with the buffer solutions in them. So, hopefully that helps.
