No problem! As a former high school teacher in the UK I'm impressed that you got your students to go onto You Tube to make comments about the video. It sounds like a useful homework task that I will be setting my students when I go back into the classroom. Thanks for the comments.
Um... To anyone confused about the sudden influx of positive posts, a few chemistry classes were asked to watch and post responses to this video as part of a homework. Anyways, the technique demonstrated was solid, and carried out in a manner that was sufficient- not lacking in anything, and not full of useless fluff either.
is it advisable to start with 0.0 for the titration though... Nearing the end point, you should be releasing the acid in dropwise manner. This is not accurate
