Question Details: calculate the ph of a buffer solution prepared by dissloving 5.00 gof acetic acid and 5.00 g of sodium acetate in sufficient water toyield a final volume of 1000.0 ml
calculate the ph of the bufferprepared above if .01 mols of NaOH is added to this buffer. assumeno change in final volume Question Details: calculate the ph of the bufferprepared above if .01 mols of NaOH is added to this buffer. assumeno change in final volume Question Details: calculate the ph of a buffer solution prepared by dissloving 5.00 gof acetic acid and 5.00 g of sodium acetate in sufficient water toyield a final volume of 1000.0 ml

Explanation / Answer

We Know that :       According to Henderson'sEquation :         pH = pKa + log [ salt ] / [ Acid ]               = 4.7447 + log [ 0.061 ] / [ 0.0833 ]                = 4.6093      CH3COOH  + NaOH -----> CH3COONa + H2O          0.0833          0.01                    0.01                          In this case NaOH acts as Limiting reagent          pH = 4.7447 + log [ 0.01 ] /   [ 0.0733 ]                  =   3.8795
