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.

Cesium sulfate is a typical solid whose solubility decreases a. with increasing temperature. b. only if the pressure decreases.

ipn [44]

cesium sulfate solubility decreases with decrease in temperature (answer C) change in temperature led to the change in kinetic energy.The lower kinetic energy the lower the solubility.Decrease in temperature led to lower kinetic energy hence lowering the solubility.
