Here are some examples of the nomenclature of p-Block Elements Group 17 Oxoacids of halogens:
- Chloric acid (HClO3): This oxoacid contains chlorine in the +5 oxidation state and has three oxygen atoms. The suffix “-ic” indicates the higher oxidation state of chlorine.
- Hypochlorous acid (HClO): This oxoacid contains chlorine in the +1 oxidation state and has one oxygen atom. The prefix “hypo-” indicates the lowest oxidation state of chlorine.
- Perchloric acid (HClO4): This oxoacid contains chlorine in the +7 oxidation state and has four oxygen atoms. The prefix “per-” indicates the highest oxidation state of chlorine.
- Chlorous acid (HClO2): This oxoacid contains chlorine in the +3 oxidation state and has two oxygen atoms. The suffix “-ous” indicates the lower oxidation state of chlorine.

Case Study on p-Block Elements Group 17 Oxoacids of halogens
One example of the use of p-Block Elements Group 17 Oxoacids of halogens is in the treatment of water. Chlorine is commonly used to disinfect water and kill harmful bacteria, viruses, and other microorganisms that may be present. This is typically done by adding chlorine gas or a chlorine-containing compound such as sodium hypochlorite to the water.
However, chlorine can also react with organic matter in the water to form potentially harmful byproducts such as trihalomethanes (THMs). These byproducts have been linked to a variety of health problems, including cancer and reproductive issues.
To address this issue, p-Block Elements Group 17 Oxoacids of halogens such as chloramines (compounds containing both chlorine and ammonia) have been developed as an alternative to chlorine for water treatment. Chloramines are less reactive with organic matter than chlorine, so they produce fewer THMs and other harmful byproducts.
In addition, chloramines are more stable than chlorine, so they can provide longer-lasting disinfection. This makes them particularly useful in large water treatment facilities, where it may be difficult to maintain a consistent level of chlorine throughout the entire water distribution system.
However, there are some potential drawbacks to the use of chloramines. For example, they may be less effective than chlorine at killing certain types of bacteria, viruses, and other microorganisms. In addition, they can also produce their own set of harmful byproducts, although these are typically less toxic than THMs.
Overall, the use of p-Block Elements Group 17 Oxoacids of halogens such as chloramines represents an important application of these compounds in the field of water treatment. By providing an alternative to chlorine, these compounds can help to reduce the formation of potentially harmful byproducts while still providing effective disinfection of water.
