A student must make a buffer solution with a pH of 4.00. Determine which weak acid is the best option to make a buffer at the specified pH. phosphoric acid, K₁= 7.52 × 10³, 1.00 M propionic acid, K, 1.34 x 10-5, 3.00 M formic acid, K, 1.77 × 10, 2.00 M acetic acid, K, 1.75 x 10,5.00 M - X Determine which conjugate base is the best option to make a buffer at the specified pH. sodium dihydrogen phosphate monohydrate, NaH, PO H₂O sodium acetate trihydrate, CH, COONa 3 H₂O sodium formate, HCOONa sodium propionate, CH, CH₂COONa The final volume of buffer solution must be 100.00 mL and the final concentration of the weak acid must be 0.100 M. Based on this information, what mass of solid conjugate base should the student weigh out to make the buffer solution with a pH of 4.00? mass= Based on this information, what volume of acid should the student measure to make the buffer solution? volume= 8 mL

I need help with the bottom two problems

A student must make a buffer solution with a pH of 4.00. Determine which weak acid is the best option to make a buffer at the specified pH. phosphoric acid, K₁ = 7.52 × 103³, 1.00 M propionic acid, K₁ = 1.34 × 10-5, 3.00 M formic acid, K₁= 1.77 × 104, 2.00 M acetic acid, K₁= 1.75 x 10,5.00 M Determine which conjugate base is the best option to make a buffer at the specified pH. sodium dihydrogen phosphate monohydrate, NaH₂PO4. H₂O sodium acetate trihydrate, CH, COONa 3 H₂O sodium formate, HCOONa sodium propionate, CH, CH₂COONa The final volume of buffer solution must be 100.00 mL and the final concentration of the weak acid must be 0.100 M. Based on this information, what mass of solid conjugate base should the student weigh out to make the buffer solution with a pH of 4.00? mass= Based on this information, what volume of acid should the student measure to make the buffer solution? volume = g mL
