Maleic acid is a carbon-hydrogen-oxygen compound used in dyeing and finishing fabrics and as a preservative of oils and fats.
In a combustion analysis, a 1.054- sample of maleic acid yields 1.599 of and 0.327 of.
When 0.609 of maleic acid is dissolved in 25.00 of glacial acetic acid, the freezing point drops by 0.82 . Maleic acid does not ionize in glacial acetic acid, which has a freezing-point depression constant of.
In a titration experiment, a 0.4250- sample of maleic acid is dissolved in water and requires 34.03 of 0.2152 for its complete neutralization.
The of 0.215 of maleic acid in 50.00 of aqueous solution is found to be 1.80.
