Homework Help: Is benzoic acid soluble in water ?

  1. Aug 19, 2009 #1
    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.
