Answer:doing background research about your question
Explanation:
Prior to the formulation of a research hypothesis, a scientist does extensive background research on the question he is researching. This background search will reveal likely cause and effect relationships which could now be formulated into a hypothesis and tested by experiments. A hypothesis is the result of painstaking research into a problem. A hypothesis can only be formulated after the research question has been properly understood via background research.
The deprotonated organic acid (RCO2-) and protonated organic base (RNH3+) go into the aqueous layer because Organic compounds that are neither acids or bases do not react with either NaOH or HCl and, therefore remain more soluble in the organic solvent and are not extracted.
