The following rules need to be know to know the correct answer. It is important to include what the following answer choices are.
The concept of compound is probably as old as the concept of "element". Robert Boyle, the key figure in the transition from alchemy to chemistry, was one was one of the first to try to distinguish "compounds" from other types of matter.
Examples:- solid, liquid, gas- soluble in water or insoluble- organic or inorganic- acidic, basic, neutraletc.
Weak soluble ionic compounds do depend greatly on the solution's ph. Not all compounds depend on the pH though because those that have stronger ionic compounds do not need to depend on the ph.
no u cant classify everything
To 'classify' means to group into a certain category.
Organic compounds
classify
All organic compounds contain carbon; most inorganic compounds doesn't contain carbon.
I classify that as an overstatement. It is true that a great many ionic compounds are highly soluble in water, but not all of them.
Solid
a trapizoid
air = solution milk = heterogeneous mixture water= compound
