Provide the name of the oxyanion of the acid HNO2(aq)
I ENTERED Carbonate ion BUT ITS WRONG
Nitrite ion
not unexpected, since there is no Carbon present.
Did you try Nitrite?
Carbonate is CO3
The correct name of the oxyanion for the acid HNO2(aq) is nitrite ion (NO2-).
To determine the name of the oxyanion of the acid HNO2(aq), we first need to understand the concept of oxyanions.
Oxyanions are negatively charged ions that contain oxygen and are formed by combining oxygen with a nonmetal or a polyatomic ion. In this case, the oxyanion is derived from the acid HNO2(aq), which is nitrous acid.
To find the name of the oxyanion, we need to consider the oxidation state of nitrogen in the acid. In nitrous acid (HNO2), nitrogen has an oxidation state of +3.
To determine the name of the corresponding oxyanion, we know that:
- If the oxidation state of nitrogen is +3, the name of the oxyanion ends in "-ite."
- If the oxidation state of nitrogen is +5, the name of the oxyanion ends in "-ate."
In the case of HNO2(aq), since the oxidation state of nitrogen is +3, the oxyanion would end in "-ite."
So, the name of the oxyanion for the acid HNO2(aq) is nitrite ion (NO2-).
