Which acids have hydro- as part of their name?
H₂SO₃
HBr
HClO₂
HF
HNO₃
Answer (2)
The acids that have 'hydro-' in their names from the provided list are hydrobromic acid (HBr) and hydrofluoric acid (HF). These represent binary acids consisting of hydrogen and one other element. Thus, the correct answer is oxed{HBr, HF} .

Identify the chemical formulas of the acids.
Determine the names of the corresponding acids.
Check if the name of each acid contains the prefix 'hydro-'.
The acids with 'hydro-' in their names are HBr and HF. H B r , H F
Explanation
Understanding the Problem We are given a list of chemical formulas and asked to identify which of the corresponding acids have 'hydro-' as part of their name. The presence of 'hydro-' in an acid's name indicates that the acid is a binary acid, meaning it consists of hydrogen and one other element.
Identifying the Acids Let's examine each chemical formula:
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.
Final Answer Therefore, the acids with 'hydro-' in their names are hydrobromic acid (HBr) and hydrofluoric acid (HF).
Examples
Acids are essential in many chemical processes, both in the lab and in industry. Knowing the naming conventions for acids, like when to use the prefix 'hydro-', helps chemists accurately identify and communicate about these substances. For example, hydrofluoric acid (HF) is used in etching glass, while sulfuric acid ( H 2 S O 4 ) is widely used in the production of fertilizers and detergents. Correctly naming these acids ensures safety and precision in chemical applications.
