benzoic acid salt water uses

One Part of Chemistry: Recrystallization

In this experiment the benzoic acid is dissolved in hot water while only a little amount of benzoic acid are able to dissolve in cold water The benzoic acid cannot dissolve well in cold solution because of its hydrophobic benzene ring However the carboxyl group -COOH that attached to the benzene ring allows some of the benzoic acid

Solubility Thermodynamic Properties and Derived

The solubility of benzoic acid in (acetic acid + water) and (acetic acid + toluene) binary mixtures has been investigated by the gravimetric method The study was carried out at different mass fractions of acetic acid ranging from 0 1 to 0 8 at 299 15 K The results indicated that the solubility of benzoic acid in both binary mixtures exhibited an increasing trend with an increase in the

Why Is Benzoic Acid Poorly Soluble In Cold Water

Benzoic acid dissolves poorly in cold water because of polar carboxylic group the bulk amount of the benzoic acid molecule is non-polar It is only the carboxylic group that is polar there are no internal stabilizing structures that favor carboxylate group -COO (-) over carboxylic acid

2-ethoxybenzoic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950C is brought in contact with it Thus it can be concluded that 2-ethoxybenzoic acid is not flammable at high temperature However since such high temperatures are not found under normal circumstances of transportation and use thus 2-ethoxybenzoic acid

Benzoic Acid

Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water The avoidance of organic solvents for the recrystallization makes this experiment particularly safe This process usually gives a yield of around 65% the solubility of benzoic acid in over 40 solvents with
