Answer:
d. pair
Explanation:
because,H3PO4 is a strong acid
Answer: Option (A) is the correct answer.
Explanation:
Chemical equation for the given reaction is as follows.

And, the expression to calculate pH of this reaction is as follows.
pH = ![pk_{a} + log \frac{[HCOO^{-}]}{[HCOOH]}](https://tex.z-dn.net/?f=pk_%7Ba%7D%20%2B%20log%20%5Cfrac%7B%5BHCOO%5E%7B-%7D%5D%7D%7B%5BHCOOH%5D%7D)
As the concentration of
is directly proportional to pH. Hence, when there occurs a decrease in the pH of the solution the
will also decrease.
Thus, we can conclude that the statement, HCOO will accept a proton from HCl to produce more HCOOH and
, best supports the student's claim.
