In today's experiment, we'll be conducting the titration of vinegar. Now, vinegar is a mixture of acetic acid and water, and the titration will be used to determine the concentration of acetic acid and vinegar. So before we begin, we're going to make sure we prime our beer. So to prime our beer, we're going to be using some distilled water to ensure that all of our sides are evenly coated. And you want to do this a couple of times. As we prime the beer, we'll add sodium hydroxide at eye level using our stool. So next thing we'll do is ensure that the tip has no air bubbles and that we've primed it to this one. So I'll open the beer and let some drain through before closing it tight and reading the initial beer rep reading. So now that we've primed it and released any air bubbles from the tip, we're going to do an initial reading of the beer rep, which is 0.5 mils. From there, we'll take our early Mayer flask and fill it with our 5 mils vinegar. We will also add our distilled water into our early Mayer flask. Now because I don't have a lab partner, I'll be using a stir plate to make sure that the solution is being stirred throughout the entire experiment. So I'll let that stir initially to make sure that the solution is nice and even throughout. Once that's stirring, I will add 5 drops of our phenophylene, which is our indicator solution. This indicator solution will give us a visual clue as to when our equivalent point has been reached. Now we can begin our titration. So I'm going to open the beer rep and we're going to see a color change as we add more and more sodium hydroxide into our vinegar solution. And initially you won't see any color change that's permanent or persistent. So just keep an eye on what's happening inside the flask. If you saw, there is some pink that's beginning to appear and is becoming more persistent. So I'm going to slow down the titration just a bit so we add the drops of sodium hydroxide rather than a long stream. So at this point, I'm beginning to see the pink color more persistently. So I'm going to start adding drop wise to ensure I don't pass the equivalent point and the color change. So once we've reached the equivalent point, our solution should be a very light pink color. So now we'll record the final beer rep reading. And for my case, it is 42.1. Once complete, we can rerun this experiment for a second trial and then average our results. For our second trial, I filled up our sodium hydroxide solution in our beer rep. And just as a note, you do not have to start at zero. For example, in my second trial, I started at 2.4 mils. Before we get started, I have already added my vinegar and water to the early-mire flask. So now I'll add my five drops of phenophylene, my indicator solution. And then I'll put it on my early-mire flask on the stir plate and let that mix just before adding my sodium hydroxide. So I'll begin my titration with a big stream coming down. And I'll make sure to keep an eye on the pink color as it becomes more persistent. So we're doing a second trial to make sure that our initial trial is accurate and that we've considered any possible errors that might have come about in our first trial. And I've started to slow down the amount of sodium hydroxide that's coming down because I'm seeing the pink color become more persistent. And what I'll do right now is called a split drop where I'll turn the softcock really quickly to get one drop in rather than letting a lot of the solution come from. And once again, once we've reached our equivalent point, our solution will turn a very faint pink color. And so our final volume is 44.5 Nuts.
