If the pka of hcho2 is 3.74 and the ph of an hcho2/nacho2 solution is 3.89, it means that

Hi, the question has some missing part. The complete question should be " If the of is 3.74 and the pH of an solution is 3.89, it means that -

(a)

(b)

(c)

Which of the options are true?"

Option (c) is true.

Explanation:

is an weak acid-conjugate base buffer. Hence, in accordance with Henderson-Hasselbalch equation-

Here, pH = 3.89, of = 3.74

So,

or, = 1.41 (>1)

So,  

or,

Hence, option (c) is correct.

ok whats the question if not i cannot you i need question and need a thing to answer
