I need help for number 5 part b and c I Review | Constants | Periodic TableWhen a solution contains a weak acid and its conjugate base or aweak base and its conjugate acid, it will be a buffer solution.Buffers resist change in pH following the addition of acid or base.A butfer solution prepared from a weak acid (HA) and its.conjugate base (A) is represented asPart AWhat is the pH of a buffer prepared by adding 0.809 mol of the weak acid HA to 0.305 mol of NaA in 2.00L of solution? The dissociation constant K. ofHA is 5.66 x 107HA(aq) - H*(aq) + A (aq)The buffer will follow Le Châtelier's principle. If acid is added, thereaction shifts to consume the added H, forming more HA.When base is added, the base will react with H, reducing itsconcentration. The reaction then shifts to replace Ht through thedissociation of HA into H and A":In both instances, HExpress the pH numerically to three decimal places.> View Available Hint(s)pH = 5.823tends to remain constant.SubmitThe pH of a buffer is calculated by using the Henderson-Hasselbalch equation:Previous AnswersA]v CorrectpH = pK, + logHASince both the acid and base exist in the same volume, we can skip the concentration calculations and use the number of moles in theHenderson-Hasselbalch equation to calculate the pH. The answer will be the same.Part BWhat is the pH after 0.150 mol of HCl is added to the buffer from Part A?
