    So yesterday I was on your stoichiometry Playlist starting with 6muffins,was like"oh sir are u kidding?!so now we are baking"🤣🤣but it assisted me a lot because I paused this vid tried it on my own nd and I got it ryt... U rock sir, big time!!!!

      I know right... 😂. I try to make my examples very relatable. Look at you now, a whole champion on Stoichiometry.
      Thank you very much showing appreciation

    sir thank you so much I watched your videos on stochiometry nearly the whole day before I came to try this question( I never tried back titration ever) and with one try I got it right the steps everything

    When it came around 20:07 and you said pure aluminium! I laughed loud, it was a tense session dealing with Magnesium but cracked me up for some reason 🤣🤣. Anyway 0.0165 x 24.3 = 0.40095 g 😡. But at least the memo has a range. This lesson was helpful. Thank you

    So if i react NaOH with something and some NaOH remains after that. Does the concentration remain the same? And if yes, why does it remain the same?

    • @MlungisiNkosi
      @MlungisiNkosi  3 ปีที่แล้ว +4

      I always make an example with Oros (my favourite summer drink, yummy!!!). Suppose you make a mixture into a jug... Does the taste change as you use it? No... The taste is concentration.
