Select all the correct answers.
Which acids have hydro- as part of their name?
$H _2 SO _3$
HBr
$HClO _2$
HF
$HNO _3$
Answer (2)
The acids that have 'hydro-' as part of their name from the given list are HBr (hydrobromic acid) and HF (hydrofluoric acid). The other acids do not qualify as binary acids and therefore do not contain the 'hydro-' prefix. In total, the selected correct answers are HBr and HF.
;
Identify binary acids as those containing hydrogen and one other element.
Check each acid for the 'hydro-' prefix.
HBr (hydrobromic acid) and HF (hydrofluoric acid) have the 'hydro-' prefix.
The correct answers are HBr and HF.
Explanation
Identifying Binary Acids We need to identify which of the given acids have the prefix 'hydro-' in their name. This prefix is typically used for binary acids, which are composed of hydrogen and one other element.
Examining Each Acid Let's examine each acid:
H 2 S O 3 : This is sulfurous acid. It does not have 'hydro-' in its name.
HBr: This is hydrobromic acid. It has 'hydro-' in its name.
H Cl O 2 : This is chlorous acid. It does not have 'hydro-' in its name.
HF: This is hydrofluoric acid. It has 'hydro-' in its name.
H N O 3 : This is nitric acid. It does not have 'hydro-' in its name.
Conclusion Therefore, the acids with 'hydro-' in their name are HBr and HF.
Examples
Understanding acid nomenclature is crucial in chemistry. For example, in a lab setting, correctly identifying acids is essential for safe handling and conducting experiments. Hydrochloric acid (HCl), a common 'hydro-' acid, is used in various industrial processes, such as pickling steel, and in the production of organic compounds. Knowing the naming conventions helps prevent errors and ensures accurate communication in scientific contexts.
