In this question for dissociation of NH4OH can't we write as in equillibrium condition c(1-@) c@ c@ . Is there a specific reason for what it has done by mole method .?
You can solve this question by that too.
What is the answer?
Answer is 4.92
Finally Here conc.of NaCl and HA is equal.
I solved this problem before but there pH is given as 5
Yes I am getting pka = 4.92
Yes bro its correct , can you please elaborate your working?
At end point of titration
moles of HA=moles of NaOH added=3.612
