I just have these two questions:

1. If an organic compund(ie benzoic acid) dissolves in diethyl ether(ie. soluble in diethyl ether) are these types of reaction in which a organic compund dissolves in diethyl ether or water a physical reaction(ie. not chemical reaction)?

2.  If a organic substance dissolves in water, then how come it is unnecessary to test its solubility in any aqueous soultion(such as HCl, NaOH, or NaHCO₃)?

1.  Yes.  In most dissolution reactions, no covalent bonds are broken or formed (however, some compounds dissolve by reacting with water in which case dissolution is a chemical reaction.  For example, carbon dioxide dissolves as follows:

CO₂ + H₂O --> H₂CO₃)

2.  What is a major component of all aqueous solutions? 

(note: I slightly disagree that it is unnecessary to test its solubility in these other aqueous solutions as the solubility can change).
