Description of the term solubility

When a soluble substances dissolves in water, its particles are so small and are thinly spread throughout the solution, that cannot be seen by the naked eye.

As a result of solubility the solution appears

transparent not cloudy

Different substances

show different degrees of solubility

what is a general statement of the relationship between solubility and temperature?

As temperature increases solubility increases

exception of solubility and temperature general relationship

Cerium Sulphate

Concentration is a measure of

Of how much of  solute is contained per volume of solution

It can be measured

Concentration (g/L): Mass of solute (in grams) ÷ Volume of solution (in litres)
Molarity (mol/L): Number of particles (expressed in moles) per litre of solution

substances containing the following ions are generally soluble

SNAPE format

SNAPE acronym

Sodium, nitrate, ammonium, potassium and ethanoate

Applications of Solubility (health)

will vitamins or medicines dissolve in the human body when ingested?

Applications of Solubility (Environmental pollution)

will a toxic substance dissolve in natural water systems and be available for plant uptake and therefore the food chain

Applications of Solubility (water purification)

contaminants can be removed from water by precipitating and filtering them

Applications of Solubility (resources industry)

precipitation reactions are used to purify compounds
