SUMMARY

Benzoic acid is slightly soluble in water, with a solubility of 2.9% at 20°C, as confirmed by the Material Safety Data Sheet (MSDS). While some sources may claim it is insoluble or only soluble in hot water, the definitive data indicates its limited solubility at room temperature. Benzoic acid is a white powder or crystal with a melting point of 122°C and a boiling point of 249°C. It is also soluble in various organic solvents, including alcohol and ether.

PREREQUISITES
  • Understanding of solubility concepts in chemistry

I've looked at a few websites and some say it is slightly soluble,some say it is insoluble in water and others say it is soluble only in hot water.

I'm not sure which one is true.

Hope someone can help.
Thank you.
