Question

The solubility of $ KN{{O}_{3}} $ at $ 313 $ kelvin is $ 62 $ gram what mass of $ KN{{O}_{3}} $ would be needed to produce a saturated ________.

Answer 1

Hint: We know that the lower temperatures, solubility generally decreases for a saturated solution and at higher temperatures, solubility of the salt increases but it depends on the type of salt $ \left( KN{{O}_{3}} \right) $ we are looking at.

Complete answer:
The term solubility product is generally applicable for frugally soluble alts. It is the maximum product of the molar concentration of the ions (raised to their appropriate powers) which are produced due to dissociation of the compound. Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is restrained in terms of the maximum amount of solute dissolved in a solvent at balance. Solubility is the new bond formation amongst the solute molecules and solvent molecules. In terms of quantity, solubility is the maximum concentration of solute that dissolves in a known concentration of solvent at a given temperature.
The resulting solution is called a saturated solution. Certain substances are soluble in all proportions with a given solvent, such as ethanol in water. This property is known as miscibility. Under numerous conditions, the balance solubility can be surpassed to give a so-called supersaturated solution, which is metastable. This is the maximum amount of solute that can be dissolved in water at 313K. The solution is saturated at that temperature.
 $ Mass\text{ }KN{{O}_{3}}=\dfrac{62}{2}=31g\text{ }. $ $ KN{{O}_{3}} $ soluble in $ 50g\text{ }{{H}_{2}}O $ at $ 313K. $

Note:
Remember that the solution which contains the maximum amount of solute dissolved in a given amount of solvent at a particular temperature and which cannot dissolve any more amount of solute at that temperature is known as a saturated solution. Solubility is measured in terms of the maximum amount of solute dissolved in solvent at equilibrium point.
