Your desired ph is 4.22 for an aetate buffer system (hc2h3o2/nac2h3o2) of total volume 300.0 ml. what will be the volume of acid and the volume of conjugate base needed to prepare the 300.0 ml buffer solution? the pka of acidic component = 4.70. (note: molarities of all reagents in the buffer system are 0.1 m; and take the closest whole number volume ratio using a round-off rule.)

answer; i believe the correct answer is (solid gold);

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
