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.)

\[ \text{[Input Box]} + \text{[Input Box]} \rightarrow \text{[Input Box]} + \text{[Input Box]} \]
