This is Experiment 5 pH titration of acetic acid with sodium carbonate, pH titration. So we're going to actually do the titration now. I've got done a couple things as far as the pH titration part of the lab at a time. So I got my 150mhz of vinegar. I then conditioned my pipette with the vinegar. Pipeted 20mhz of vinegar. 2.00mhz at a time. So 10 times. Then I conditioned my pipette actually with distilled water after the vinegar. And then with the sodium carbonate solution. And now I'm ready to go. So I've got my sodium carbonate solution. I don't need my extra vinegar, those for the other titrations. I've got my titration solution right here. I've got my pH tester, which I've already calibrated. And I'm ready to go. And I've got my data table. And it says with 0ml. And then my total is going to be 0. I'm going to take the pH. I'm going to turn it on. I'm going to test the pH. And you can see, I don't have a lot of solutions. So I'm going to curve it a little bit and throw it for 5 to 10 seconds. And as long as that glass piece is under the water, under the solution in this case, we're good. And my initial pH. Do you think you've been under there and show it to you? I'll focus on it, but it's 1.86. And I'm actually not going to rinse it with distilled water each time. Now I am going to add two milliliters, normally two milliliters. Actually. Yeah, I keep it there. I'm just going to put it to the side. I want to put my two milliliters in without editing the pH tester. It's adequate to 2.0 line. You'll notice when you add the sodium carbonate, you get some bubbles in there, give it 5 or 10 seconds of swirling, then record the pH. And I'm going to talk there about 5 or 10 seconds. Let it sit. You should get a constant number. It is staying at 3.34. And the way I'm filling out this chart. I put in my two milliliters, two milliliters. My actual amount that I get each time I put it right at that 2 point. That 2 milliliters line is 2.01 from Experiment 2. I'll fill that in later. And then I'll add everything up to my running total after the finished year. Alright, so. Now I'm going to add two more milliliters. This is close to that line. Minescus. Empty everything in there. Bubbles. I guess we'll give it 5 or 10 seconds. I'm going to add the bubbles. I'm going to add the bubbles. I'm going to add the bubbles. I'm going to add the bubbles. I'm going to add the bubbles. I guess we'll give it 5 or 10 seconds for the bubbles to go away. And I get my new pH value. That's pretty stable. It's actually flicking between two different numbers. That's pretty stable. Now for the rest of this titration, you're going to add 2 milliliters. 2 milliliters until you get somewhere around pH 5 or 6. Then you're going to start adding 1 milliliters at a time. Nomino 8 and then 0.5 milliliters at a time. And once you get to pH 6, you should be only adding 0.5 milliliters at a time. Keep track of every single time that you do it. And go all the way through to a pH of... Well, let's say this, until the pH flattens out. Then after the big rise in pH around pH 7 to 8, allow the pH to flat. Now give it 3 or 4 more points. You should be doing 2 milliliters at a time after it flattens out for 3 or 4 points as well. Thank you.
