21. Free base cocaine separates as an oily layer, floating on the top of the now leftover aqueous phase . 22. The partition coefficient is defined at a specified temperature and, if applicable, pH of the aqueous phase . 23. The organic phase is slowly injected in the aqueous phase which then is agitated to form the colloidal suspension. 24. AOPs are aqueous phase oxidation methods consisting of highly reactive species used in the oxidative destruction of target pollutants. 25. :The cream in whole ( raw ) milk naturally separates from the aqueous phase and rises to the top. 26. Olfactory transduction begins with the movement of odorants from the air phase to the aqueous phase in the olfactory mucus. 27. In this method the organic phase is added to the aqueous phase under conditions of high agitation which form an emulsion. 28. This is useful for when the aqueous phase is removed from the solution in order to obtain a pure nucleic acid sample. 29. The dissolved components of petroleum mixtures such as crude oil can become subject to the transport mechanisms of the bulk aqueous phase . 30. The concentration in aqueous phase is now 5.6 * 10 ^-5 M and the new partition coefficient is 22.
