A solution( or True solution) is a homogenous mixture of two or more components in which intermingling particles are in the dimensional-level of atoms or molecules. A solution consists of solute and solvent. A solute is the substance that gets dissolved and the substance in which solute gets dissolved is called solvent.
Concentration of a Solution Edit
The concentration of a solution means the quantity of solute dissolved per unit volume of solution or per unit quantity of solvent.
Expressing Concentration of Solutions: Edit
- Mass Fraction: is defined as the mass of the component divided by the total mass of the solution.
- Mole Fraction: is defined as the moles of component divided by the total moles of solution.
- Molality: is defined as the number of moles of solute dissolved per kilogram of solvent. It is denoted by m. The unit of molality is mol/kg.
- Molarity: is defined as the moles of solute contained in 1 litre of solution(Or millimoles/1 cc solution). It is denoted by M. Its unit is mol/L or millimol/mL.
- Normality: is defined as the number of gram equivalents of solute contained in one litre of solution or it can be taken as number of milli equivalents(m.eq) in 1 cc(mL) of solution. It is denoted by N. Relation between Normality and Molarity:
