Maleic acid is a carbon-hydrogen-oxygen compound used in dyeingand finishing fabrics and as a preservative of oils and fats.
* In a combustion analysis, a 1.054-\rm g sample of maleic acidyields 1.599 \rm g of \rm CO_2 and 0.327 \rm g of \rm H_2O.
* When 0.609 \rm g of maleic acid is dissolved in 25.00 \rm g ofglacial acetic acid, the freezing point drops by 0.82 ^\circ \rm C.Maleic acid does not ionize in glacial acetic acid, which has afreezing-point depression constant of K_{\rm f}=3.90~^\circ {\rmC}/m.
* In a titration experiment, a 0.4250-\rm g sample of maleic acidis dissolved in water and requires 34.03 \rm mL of 0.2152 M \rm KOHfor its complete neutralization.
* The \rm pH of 0.215 \rm g of maleic acid in 50.00 \rm mL ofaqueous solution is found to be 1.80.
Part A
Determine the empirical formula for maleic acid. Enter the atoms inorder of \rm C, \rm H, and \rm O.
Part B
Determine the molecular formula for maleic acid. Enter the atoms inorder of \rm C, \rm H, and \rm O.
Express your answer as a chemical formula.
Part C
Based on the titration data, how many ionizable \rm H atoms are ineach molecule of maleic acid, \rm C_4H_4O_4?
Express your answer as an integer.
I GOT THE PART A and B which is CHO and C_4H_4O_4 respectively, cananyone help me for part C?
