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)![[HCHO_{2}]< [NaCHO_{2}]](/tpl/images/0643/4545/97796.png)
Which of the options are true?"
Option (c) is true.
Explanation:
Here, pH = 3.89,
of
= 3.74
So,![3.89=3.74+log(\frac{[CHO_{2}^{-}]}{[HCHO_{2}]})](/tpl/images/0643/4545/d55a8.png)
or,
= 1.41 (>1)
So,![[CHO_{2}^{-}] [HCHO_{2}]](/tpl/images/0643/4545/877d3.png)
or,![[NaCHO_{2}] [HCHO_{2}]](/tpl/images/0643/4545/6ef0b.png)
Hence, option (c) is correct.
