A buffer solution is made by mixing 0.102 moles of sodium nitrite (NaNO2) in 1.00 L of 0.125 M nitrous acid (HNO2).Ksp = 4.5*10^-4
a.) What is the pH of this buffer solution? (Neglect the volume change that occurs with addition of solid sodium nitrite)
b.) Calculate the pH when 2.00 mL of 0.0275 M NaOH are added to 50.0 mL of buffer solution.
