appreciate it :)

If I calculate the concentration of HX for 4.3 correctly but not sure if it’s right in the exam should I just use the one given in 4.4? Thank you, Great video, very helpful!

[@pinkiepiek1d808]

Yes always use the exam one if you are unsure

[@balajipalaniappan6804]

On part 4.3 wouldn’t HX be the weak acid instead of NaOH since that is a strong base

[@adrianhall306]

Actually never mind I wasn’t thinking

[@ravjayakodi2746]

@ 5:40 why do we use the end point moles when the Q asked for the concentration in the OG solution ? I don't get that bit

[@Xlr8t]

i dont really know bro, sorry

[@missyfford4962]

Because at the end point the mol of OH- is equal to the initial mol of HX, this is why you get the steep change in pH.
