It is soluble in water because it
dissociates to form benzoic and sodium ions.
Solubility in water at 293K (20oC)
is 63 g/100ml.
Dissolved in water it is a
transparent colourless solution.
In addition to being soluble in
water it is also soluble in ether, chloroform and fixed oils.
- If a substance is

flash point is the lowest temperature that a liquid can form a
mixture in air close to the surface of the liquid which is ignitable. The
lower the flash point, the easier it is to set fire to the material.
is the lowest temperature at which a substance will spontaneously ignite
without the use of a spark to aid it.
carboxyl group is one in
which a carbon atom is covalently bonded to two oxygen atoms. One of the
oxygen's is double bonded to the carbon, and the other is also attached to
a hydrogen atom.
