Chapter 6: Problem 4

State whether the following statements are true or false. \(\mathrm{S}^{-2}\) is the conjugate base of \(\mathrm{HS}^{-}\)

Short Answer

Expert verified
Answer: True

Step by step solution

01

Understand the concept of conjugate base

A conjugate base is formed when an acid loses a proton (H+). When an acid donates a proton to a base, the acid becomes its conjugate base. The relationship between an acid and its conjugate base is essential in understanding acid-base reactions.
02

Identify the acid and base in the given statement

In this exercise, we are given two species: \(\mathrm{S}^{-2}\) and \(\mathrm{HS}^{-}\). To determine whether \(\mathrm{S}^{-2}\) is the conjugate base of \(\mathrm{HS}^{-}\), we need to find out how these two species are related in terms of gaining or losing a proton.
03

Determine if \(\mathrm{S}^{-2}\) is the conjugate base of \(\mathrm{HS}^{-}\)

To determine if \(\mathrm{S}^{-2}\) is the conjugate base of \(\mathrm{HS}^{-}\), we need to see if \(\mathrm{S}^{-2}\) is formed when \(\mathrm{HS}^{-}\) loses a proton. The equation looks like this: \(\mathrm{HS}^{-} \rightarrow \mathrm{S}^{-2} + \mathrm{H}^{+}\) In this reaction, \(\mathrm{HS}^{-}\) loses a proton and forms \(\mathrm{S}^{-2}\) and \(\mathrm{H}^{+}\). This shows that \(\mathrm{S}^{-2}\) is indeed the conjugate base of \(\mathrm{HS}^{-}\).
04

Conclusion

Based on the steps discussed above, the statement is true: \(\mathrm{S}^{-2}\) is the conjugate base of \(\mathrm{HS}^{-}\).
