Questions: CIO2 is the chlorite anion.
Once you have the anion named, the rules are as follows:
1. If the acid contains an anion with a name that ends in -ide, then change the -ide to
For example: HCl is hydrochloric acid.
2. If the acid contains an anion with a name that ends in -ate, then change the -ate to
For example: HNO3 is nitric acid.
3. If the acid contains an anion with a name that ends in -ite, then change the -ite to -
For example: HClO2 is chlorous acid.
(Note: Use of rule number 3 is far less common than rules 1 and 2.)
What is the name of the acid with the formula HClO3?
hydrochloric acid
chlorous acid
hydrochlorous acid
chloric acid
Transcript text: $\mathrm{CIO}_{2}$ is the chlorite anion.
Once you have the anion named, the rules are as follows:
1. If the acid contains an anion with a name that ends in-ide, then change the -ide to
For example: HCl is hydrochloric acid.
2. If the acid contains an anion with a name that ends in-ate, then change the -ate to
For example: $\mathrm{HNO}_{3}$ is nitric acid.
3. If the acid contains an anion with a name that ends in-ite, then change the -ite to -
For example: $\mathrm{HClO}_{2}$ is chlorous acid.
(Note: Use of rule number 3 is far less common than rules 1 and 2.)
What is the name of the acid with the formula $\mathrm{HClO}_{3}$ ?
hydrochloric acid
chlorous acid
hydrochlorous acid
chloric acid
Solution
Solution Steps
Step 1: Identify the Anion
The formula \(\mathrm{HClO}_{3}\) contains the anion \(\mathrm{ClO}_{3}^{-}\), which is known as the chlorate anion.
Step 2: Apply Naming Rule for -ate Anions
According to the rules, if the acid contains an anion with a name that ends in -ate, change the -ate to -ic.
Therefore, chlorate becomes chloric.
Step 3: Name the Acid
Combine the modified anion name with the word "acid."
The name of the acid \(\mathrm{HClO}_{3}\) is chloric acid.
