Do you have a solution whose concentration you want to determine? Then why not try a titration? Prof Al from the Chemistry Department at AUT demonstrates the dos and donts.
That's the best video to find. Looked the whole day in instruction books, but this video is so visual and a very nice and kind lecturer. Wish I'd found this 12 hours ago :D
My teacher promised that she was going to reward the first person who can perform the titration perfectly. Therefore i rushed to youtube watching heaps of videos. But your one is definitely the best one by far, i did not skip a single second of it! I rarely leave any comments on youtube, but your video was so coherent that I could not leave without leaving one! This is absolutely going to help a lot in my prac next week!
This has been the most helpful video - I've been hitting my head against the wall with my tutor, he has never given me a visual example for the end-point, just tells me "the expected colour change is colourless to pink, the expected colour change is yellow to orange" etc dependant on the titration and indicators used He tells me "just make the numbers make sense" I knew something was wrong when my phenolphaelin was turning a bright pink and he said yep that's the end-point there 😅 but I'm being told to just report the numbers and make the math correct I'm just an RTO student so thankfully this is not happening in a workplace, but still frustrating to know that I'm being taught nothing of value - when accuracy is crucial as with titrations, I feel it is essential to know exactly what the end point is supposed to look like. Thank you, wish I saw this weeks ago
Great video and it's good to know how to get rid of bubbles. Do you think it would be better to put in a small amount of titrant, clear any bubbles if they exist by the method you demonstrated and then top up the burette? By doing it this way, it would become part of the procedure and any bubbles would be cleared every time, in one go and without wasting any titrant. I absolutely love your lab by the way. It looks amazing!
My professor forbids us to use gloves in the lab, even if we're working with high-concentrated acids. I told him like a million times, that we should use them, but he just says, we're not allowed, because we should work careful, so that we don't need gloves. i recently gave up to discuss with him.
