- Describe how a cholesteric liquid crystal phase differs from a nematic phase?Under the conditions of this extractive procedure, how does aspirin become partitioned into the aqueous layer? How do we then recover this substance in a pure form from the aqueous layer? O 1) The acidic hydrogen in the carboxyl group (-COOH) of aspirin undergoes an acid-base reaction with NaOH to form the conjugate base, sodium 2-acetoxybenzoate. U 2) This ionic species then readily dissolves in water. 3) Conversely, the organic unknown does not possess an acidic residue, so no acid/base reaction can occur. 4) It therefore does dissolve in water.A state of dynamic equilibrium exists between the solid sucrose (table sugar) molecules, C12H22O11, and sucrose molecules dissolved in aqueous solution for a saturated sucrose solution. a.
