Question 4 of 4 Strong base is dissolved in 665 mL of 0.200 M weak acid (K, = 4.03 x 10-5) to make a buffer with a pH of 4.13. Assume that the volume remains constant when the base is added. HA(aq) + OH(aq) → H₂O(l) + A (aq) Calculate the pK, value of the acid, and determine the number of moles of acid initially present. PK₁ = When the reaction is complete, what is the concentration ratio of conjugate base to acid? How many moles of strong base were initially added? initial amount: [A] [HA] = amount added: mol HA mol OH
