If a buffer solution is 0.190 M in a weak acid ( a=3.6×10−5) and 0.480 M in its conjugate base, what is the pH?

Solution :

We know, pH of this solution :

Hence, this is the required solution.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
