- A solution is composed of one or more solutes, dissolved in a solvent.
- Solute is a component of a solution of a solution that is present in lesser quanity than the solvent.
- Solvent is the solution component present in the largest quanity.
- Solution of electrolytes are formed from solutes that are soluble ionic compounds.
- Compounds dissociate in solution to produce ions that nehave as charge carriers.
- Solutions of electrolytes are good conductors of electricity.
- Example sodium chloride in water.
- NaCL ->Na +Cl
- Solutions of nonelectrolytes are formed from nondissociating molecular solutes, and these solutions are nonconducting.
- A true solution is a homogenous mixture with uniform properties throughout.
- A true solution, solute cannot be isolated from the solution by filtiration.
- Particle size and the solute is about the same as that of the solvent, solvent and solute pass through the dilter paper.
- Solute particles will not settle out over time.
True solutions, colloidal dispersion and supensions
- A clear liquid in a neaker may be a pure substance, a true solution ofr a collodial dispersiom.
- Only chemical anaysis, determing the identity of all substances in the liquid, can distingusih between a pure substance and a solution.
- Pure substamce has one component, pure water.
- True solution will cotain more than one substance, with tiny particles homogenerously intermingled.
Degree of solubiility
- Relationship of polarity and solubility, rule like dissolves like was described as the dundamental condition of solubility.
- Polar solutes are soluble in polar solvents, nonpolar solutes are soluble in nonpolar solvents.
- Degree of solubility can dissolve in a given volume of solevent, is a quantative measure of solubility.
- Difficult to predict the solubility of each and every compound.
- General solubility trends are based on following consideration such as the magnitude of diffrence between polarity of solute and solvent.
