What is the conjugate base of HNO2?
Understand the Problem
The question is asking for the conjugate base of nitrous acid (HNO2). The conjugate base is what remains after an acid donates a proton (H+). In this case, when HNO2 donates a proton, the species formed is NO2-. Therefore, the question seeks to identify this species.
Answer
NO2-
The final answer is NO2-
Answer for screen readers
The final answer is NO2-
More Information
The conjugate base of an acid is formed by removing a proton (H+) from the acid. For nitrous acid (HNO2), the removal of a proton results in the formation of nitrite ion (NO2-).
Tips
A common mistake is confusing the conjugate base with the conjugate acid. Remember that the conjugate base results from the loss of a proton, whereas the conjugate acid results from the gain of a proton.
