Does stearic acid soluble in ether or NaOH? why?

A solution of benzioc acid and NaOH is mixed wid equal amount of ether, then which liquid will form top layer?

  • Answer:

    When NaOH is added to benzoic acid, the salt sodium benzoate is formed. The reaction is: NaOH + C6H5COOH -----> NaC6H5COO + H2O The salt is ionic and dissolves in the water layer. The ether layer forms on top of the water layer, which now contains the sodium benzoate. Water is more dense that the ether and doesn't mix hardly at all because the ether is nonpolar and the water is polar.
