Kindly answer with solutions. Thank you. c102 After preparing the buffer, Phoebe decided to determine the buffer capacity of the solution by titration using 0.300 M NaOH as titrant. Given the data she obtained below, calculate the preparedbuffer system's buffer capacity (B).ParameterValue/MeasurementVolume of buffer, mL 75.0Initial pH reading10.15Final pH reading11.15Final buret reading, mL 46.50Initial buret reading, mL 34.60A. ApH =B. AV NaOH (ML) =C. Moles of titrant =D. Buffer Capacity (B) = 2. Phoebe was tasked to ensure that an enzyme responsible for keeping her species from extinction remains biologically active. To do so, she needs to store it in a buffer solution with a pH of10.00. Unfortunately, only three buffer systems are available in their laboratory:Buffer System Weak Acid Component K₂Conjugate Base SaltPAHBenzoic acid, C6H5COOH 6.25 x 10-5 NaC6H5COOSADBoric acid, H3BO35.81 x 107 NaH₂BO3DOHHydrogen cyanide, HCN 6.20 X 10-10 NaCNA. In what buffer system (PAH, SAD, or DOH) will Phoebe store the enzyme?In your solution sheet, show calculations and briefly explain to support your answer.B. Write the equilibrium reaction involved in the buffer system. Write your answer on your solution sheetC. Calculate the amount (in mL) of the 2.00 M stock solution (pH 10.00) of the same buffer system needed to prepare 250 mL of a 0.650 M buffer pH 10.00.
