A buffer solution is made that is 0.432 M in HNO2 and 0.432 M in KNO2. If K₂ for HNO2 is 4.50 x 10-4, what is the pH of the buffer solution? pH = Write the net ionic equation for the reaction that occurs when 0.118 mol KOH is added to 1.00 L of the buffer solution. (Use the lowest possible coefficients. Omit states of matter.)

A buffer solution is made that is 0.432 M in HNO₂ and 0.432 M in KNO₂.
If \( K_a \) for HNO₂ is \( 4.50 \times 10^{-4} \), what is the pH of the buffer solution?
\[ \text{pH} = \] [Input Box]
Write the net ionic equation for the reaction that occurs when 0.118 mol KOH is added to 1.00 L of the buffer solution.
(Use the lowest possible coefficients. Omit states of matter.)
\[ \text{[Input Box]} + \text{[Input Box]} \rightarrow \text{[Input Box]} + \text{[Input Box]} \]
