Define the terms
1 dilution 2 concentration 3 solubility 4 Molarity
Dilution:
two basic terms dilute and concentrated solutions and both are Depending on the relative amount of solute present in Dilute solution contains a relatively small amount of a solute in a large amount of solvent like adding more water to a solution.
Concentration
concentrated arrangement contains a moderately enormous measure of solute in a limited quantity of dissolvable if the large amount of solute is dissolved in small amount of solvent that is called as concentrated solution
SOLUBILITY
It is characterized as the greatest amount of solute that can be disintegrated in 100 grams of dissolvable to plan soaked arrangement at a particular temperature different substances have different capability to dissolve in the same solvent at a particular temperature
for example: the solubility of sodium chloride in 100g of water at 100C is 39.12g whereas the solubility of silver chloride in 100g of water at 100c is 0.002g this shows that sodium chloride is much more soluble in water than silver chloride
MOLARITY:
Molarity is defined as the number of moles of solute dissolved in one dm3 of the solution molarity is the concentration unit in which the amount of solute is expressed in gram and the amount of solution is expressed in dm3
It is denoted by “M” and its unit is mol/dm3
Molarity (M) = Number of moles of solute/ volume of solution in dm3
Number of moles of solute = mass of solute/ molar mass of the solute (gmol-1)
Volume of solution in dm3
= volume of solution (cm3
/1000)
Molarity = Mass of solute (g) / Molar mass of the solute( gmol-1)× 1000/ volume of solution (cm3)
