Suppose 10 $\times$ 10^-5)

question 22

Short Answer

Suppose 10.0 mL of 2.00 M NaOH is added to (a)0.780 L of pure water and (b)0.780 L of a buffer solution that is 0.682 M in butanoic acid (HC₄H₇O₂)and 0.674 M in butanoate ion (C₄H₇O₂^-).Calculate the pH of (a)and (b)before and after the addition of the NaOH.Assume volumes are additive.(K_a,HC₄H₇O₂ = 1.5 $\times$ 10^-5)
