<h3>What is a polyatomic anion?</h3>
A polyatomic ion is an ion composed of two or more atoms. Examples: The hydroxide cation (
) and the phosphate cation (
) are both polyatomic ions.
and are the polyatomic anions because both contain more than 1 atom.
Hence,

POH=14-pH=14-2.5=11.5
pH=-log[H+]
2.5=-log [H+]
[H+]=10^-5/2
[OH-]=10^(14-5/2)=10^23/2
Answer:
See explanation
Explanation:
Chlorine is a member of the halogen family known as a toxic yellowish green gas. Inhalation of chlorine for a prolonged period of time leads to pulmonary edema. If a person comes in contact with compressed liquid chlorine the person may experience frostbite of the skin and eyes.
However chlorine is very useful in water disinfection and is preferred in water treatment because it provides residual disinfection of the treated water.
Chlorine gas may be dissolved in NaOH to form oxochlorate I which is used as a bleach in cleaning.
