Multi-Unit
A buffer solution is prepared by mixing equal volumes of \(0.20\text{ M } \text{HNO}_2\text{(aq)}\) and \(0.20\text{ M } \text{KNO}_2\text{(aq)}\). A student adds several drops of \(0.10\text{ M } \text{KOH(aq)}\) to a portion of the buffer. Which of the following is the net ionic equation for the primary reaction that occurs upon addition of the \(\text{KOH(aq)}\)?
