2019年1月8日 · Calculate A HoAc ∞ (in s cm 2 mol-1) using appropriate molar conductances of the electrolytes listed above at infinite dilution in H 2 O at 25 ° C. (a) 517.2 (b) 552.7
“Physically” the H+ is being “stored” as undissociated HOAc: If add OH-also find pH does not change because the OH-reacts with HOAc to give H2O and OAc-! [HOAc] = 0.701 and [OAc-] …
