How do you know if a substance is soluble or insoluable?

Answer 1

some substances are soluble and some arn't because it all depends on the particles. If the particles of a substance are attracted to it's own particles and not the waters then it is insoluble, but if the substance is more attracted to the water's particles then it's own's, it is soluble.

Answer 2

In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is dissolved in another substance, known as a solvent. The solvent does the dissolving.

Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a liquid solvent to form a homogeneous solution of the solute in the solvent. The solubility of a substance fundamentally depends on the used solvent as well as on temperature and pressure. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration where adding more solute does not increase the concentration of the solution.

SolubleInsoluble

Group I and NH4+ compounds

Carbonates (Except Group I, NH4+ and uranyl compounds)

Nitrates

Sulfites (Except Group I and NH4+ compounds)

Acetates (Ethanoates) (Except Ag+ compounds)

Phosphates (Except Group I and NH4+ compounds)

Chlorides, bromides and iodides (Except Ag+, Pb2+, Cu+ and Hg22+)

Hydroxides and oxides (Except Group I, NH4+, Ba2+, Sr2+ and Tl+)

Sulfates (Except Ag+, Pb2+, Ba2+, Sr2+ and Ca2+)

Sulfides (Except Group I, Group II and NH4+ compounds)

Answer 3

It All Depends On The What The Substance Is Mixed With.

example: Sugar Cannot Be Mixed With Oil But Can Be Mixed With Water

Answer 4

no because its a stupid question
