Question

Consider the reaction below. HI + H2O mc014-1.jpg H3O+ + I– Which is an acid-conjugate base pair? HI and H2O H2O and H3O+ H3O+ and I– HI and I–

Answer 1

Answer: Option (d) is the correct answer.

Explanation:

According to Bronsted-Lowry, species which donate a proton are known as acid. The species which accept a proton are known as a base.

In the given reaction, acids and bases are as follows.

    HI  +   $H_{2}O$ $\rightarrow$    $H_{3}O^{+}$           +         $I^{-}$

 Acid        Base     Conjugate acid   Conjugate base

Therefore, the acid HI loses a proton to form a conjugate base that is $I^{-}$.

Thus, we can conclude that HI and $I^{-}$ is an acid conjugate base pair.

Answer 2

Answer:

Then the correct answer is d HI and I-

Explanation:

Hello! Let's solve this!

According to bronsted-Lowry, the conjugate acid is what forms after a base accepts a proton. A conjugate base is the one formed after the acid accepts a proton.

In this problem we have the conjugate acid that is H3O +, the acid is HI, the conjugate base is I- and the base is H2O

Reaction     HI   +   H2O    ---->   H3O+    +   I-

Then the correct answer is d HI and I-
