Calculate the buffer capacity (bc) of your buffer solution before and after dilution with water, and enter the values obtained below. remember that before dilution the water volume in the flask was 25 ml. after dilution, the volume was 35 ml. the number of moles of weak acid and conjugate base will depend on the amounts added to the flask. your weak acid's molar mass is 234 and that of the conjugate base is 256.

Calculate the ratio of h+ ions to ohโ ions at a ph = 7. find the concentration of h+ ions to ohโ ions listed in table b of your student guide. then divide the h+ concentration by the ohโ concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to ohโ ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of ohโ ions at a ph = 7? mol/l what is the ratio of h+ ions to ohโ ions at a ph = 7? : 1
