I need proficient help in the following problems.

Problem- 1. Student Q prepared 50.00 mL of a buffer solution using 0.50 moles of HA and 0.50 moles of A- while Student S prepared 50.00 mL of a buffer solution using 0.25 moles of HA and 0.25 moles of A-.

a. Do the two buffer solutions have the same or different pH? Explain.

b. If 1.00 mL of 0.010M NaOH were added to the two buffer solutions, would the pH of the two solutions increase or decrease? Explain.

c. Which solution (Buffer Q or Buffer S) would show a smaller change in the pH for question (b)? Explain.
