Answer:
Explanations:
An acid is a substance that gives up hydrogen ions in solution or dissociates in solution.
A base is a substance that releases hydroxide ion in aqueous solution while an amphoteric substance is a substance that act as an acid in presence of a base and act as a base in presence of an acid.
From the given table, the following compounds are acids.
![\begin{gathered} H_3O^+ \\ HBrO_3 \\ NO_2^- \end{gathered}](https://img.qammunity.org/2023/formulas/chemistry/college/7f7j8uzm2wsqx6v762z14j9yi0wc95tm0o.png)
The bases are as shown;
![\begin{gathered} OCl^- \\ CN^- \\ C_3H_7NH_3^- \\ CH_3NH_2 \end{gathered}](https://img.qammunity.org/2023/formulas/chemistry/college/fr6lccrxv2644a4shyf61t8v6kbeelgx86.png)
The amphoteric compounds are;
![HSO_4^-](https://img.qammunity.org/2023/formulas/chemistry/college/x5ci4x7zigcet5pz5lwi9tf97qcwsy1xat.png)
