This is a simple consequence of the solvation having a positive Delta S value.
. Since benzene is the main ingredient in benzoic acid the majority of benzoic acid is nonpolar making the acid only slightly water soluble. Sodium benzoate is the sodium salt of benzoic acid used as a white crystalline or amorphous without crystal structure powder very soluble in water 66 g of sodium benzoate. However its solubility increases as the.
Benzoic acid is an organic acid first used in foods almost 100 years ago. Benzoic acid has a high solubility in hot water while poor solubility in cold water. It occurs naturally in prunes cinnamon and cloves.
The presence of the polar carboxylic group accounts for its modest solubility. Based on the p K a of 42 for benzoic acid 28 the absorption. Solving Problems In Life Science By Collaborating With the Global Scientific Community.
Most compounds become more soluble in water at high temperatures. It can easily dissolve in organic solvents like acetone benzene alcohol liquid ammonia ether. Answer 1 of 2.
The primary reason benzoic acid dissolves only slightly or poorly in cold water is that because of a polar carboxylic group the bulk amount of the benzoic acid molecule is non-polar. The most glaring evidence is the fact that the compound does not completely break down in room-temperature water. In water or cold water benzoic acid dissolves somewhat.
The free acid form is poorly soluble in water and the sodium salt. The UV-vis spectra between 200 nm to 300 nm for benzoic acid in water at acidic and basic pH is shown in Fig. Is benzoic acid soluble in water.
