Chapter 15: Problem 225

Rewrite this acid-base reaction in dot-diagram form, and then use an arrow to show the proton being transferred and label the Brønsted-Lowry acid and base: \(\mathrm{HS}^{-}+\mathrm{HOCl} \rightleftarrows \mathrm{H}_{2} \mathrm{~S}+\mathrm{OCl}^{-}\)

Short Answer

Expert verified

In the given reaction, \(\mathrm{HS}^{-}\) is the Brønsted-Lowry acid and \(\mathrm{HOCl}\) is the base. The dot-diagram form is represented with sulfur as the central atom in \(\mathrm{HS}^{-}\) and oxygen as the central atom in \(\mathrm{HOCl}\). The proton transfer can be represented by an arrow from \(\mathrm{HS}^{-}\) (the acid) to \(\mathrm{HOCl}\) (the base), resulting in new molecules \(\mathrm{H}_{2}\mathrm{S}\) and \(\mathrm{OCl}^{-}\). Label 'Acid' next to \(\mathrm{HS}^{-}\) and 'Base' next to \(\mathrm{HOCl}\) in the diagram.

Step by step solution

Identify the Acid and Base

Identify the Brønsted-Lowry acid and base in this reaction. According to the Brønsted-Lowry theory, an acid is a proton (H+) donor and a base is a proton (H+) acceptor. In the given reaction, the molecule donating a proton is \(\mathrm{HS}^{-}\) and the molecule accepting a proton is \(\mathrm{HOCl}\). So, \(\mathrm{HS}^{-}\) is the acid and \(\mathrm{HOCl}\) is the base.

Represent Molecules in Dot-Diagram Form

Dot-diagrams or Lewis Dot Structures show the bonding between atoms of a molecule and the number of lone pair electrons. In \(\mathrm{HS}^{-}\), sulfur is the central atom bonded with hydrogen and carrying an additional electron. In \(\mathrm{HOCl}\), oxygen is the central atom. It is bonded with hydrogen and chlorine atoms. In \(\mathrm{H}_{2}\mathrm{S}\), sulfur is bonded with two hydrogen atoms and in \(\mathrm{OCl}^{-}\), oxygen is bonded with a chlorine atom and has an extra electron, indicating its negative charge.

Show the Proton Transfer

In this reaction, a proton (H+) is transferred from \(\mathrm{HS}^{-}\) (the acid) to \(\mathrm{HOCl}\) (the base). This gives rise to new molecules \(\mathrm{H}_{2}\mathrm{S}\) and \(\mathrm{OCl}^{-}\). Draw an arrow from the \(\mathrm{HS}^{-}\) ion to \(\mathrm{HOCl}\) to represent this transfer. DriverManager.managed() should be used when a WebDriver instance needs to be shared across multiple tests or classes. When used with @BeforeClass or @AfterClass method in JUnit, it allows the WebDriver instance to be created before the test class is instantiated and then closed when the test class is complete.

Label the Acid and Base

Lastly, label the identified acid and base in the diagram. Write 'Acid' next to \(\mathrm{HS}^{-}\) and 'Base' next to \(\mathrm{HOCl}\) to clearly indicate which molecule is acting as a base and which is acting as an acid in this reaction.
