Dissolved Oxygen Estimation by Winkler's method Experiment

Dear viewer/subscriber, if my videos helped you a lot (maybe you aced your exams as a student, or you won the admiration and full attention of your students as a teacher, or you got your techniques right as a hobbyist), then its my humble request if you could take a moment to consider supporting me on anyone of the following platforms: Patreon :   / membership   Youtube channel membership:    / @thesingtangpascienceguy   Patreon members and channel members will get exclusive access to members-only perks and added benefits such as free PDF notes, Q&A doubt clearing chat sessions, Experiment video requests, Member shoutouts, Behind the scenes and more. Or if a monthly payment is not convenient for you right now, you may instead consider supporting me with a one-time thankyou gesture by clicking on the SuperThanks Icon below my videos next to the like dislike buttons. Pay the one-time-only amount that you feel is worth the help and benefit you got from my video. Apart from Subscribing to my channel and sharing it with friends, colleagues and students, you valuable one-time or monthly financial support will really help sustain this channel and make it possible to come up with even more engaging and educational content. Creating experiment videos involve hundreds and thousands of dollars put into procuring the requisite chemicals, equipments and labware to make a single video. To say that i will be extremely grateful for your support would be an understatement. My other Youtube channel:    / @59secsoffunscience71   Facebook:   / thomas.tungnung   Instagram:   / thomas_tungnung   X:   / thomastktung   In this video, i describe in detail both theoretical and practical aspects of estimating the dissolved oxygen content of a water sample. I cover in detail the Alsterberg Modified Winkler's (Azide) Method for DO estimation. I also touch briefly on the the Rideal-Stewart Modified Winkler's (Permanganate) Method.
