A100.0 ml solution containing 0.923 gof maleic acid (mw=116.072 g/mol) is titrated with 0.265 m koh. calculate the ph of the solution after the addition of 60.0 ml of the koh solution. maleic acid has pkapka values of 1.92 and 6.27.

ph=

at this ph, calculate the concentration of each form of maleic acid in the solution at equilibrium. the three forms of maleic acid are abbreviated as h2m, hm−, and m2− which represent the fully protonated, intermediate, and fully deprotonated forms, respectively.

[m2−]=__m

[hm−]=__m

[h2m]=__m
