The strength of the solution can be measured by two ways as comparison method and Strength determination method. The comparison method is classified as the dilute solution and concentrated solution. But this method is not suitable for the determination of the solution. The measurement of the solution can be determined by the strength of the solution methods. It is the real method for the determination of the solution as it involves different sub method for the determination they are
1. Percentage solution: It is categorized in the three ways.
Percentage by weight: It is one of the way of measuring the solution strength. It is defined as the amount of solute dissolved in the 100 gm of its solution expressed in %.
Percentage by volume: It is defined as the amount of solute dissolved in a 100 ml of the solution express in the %.
Percent volume ratio: It is defined as the amount of solute in ml dissolved to make 100 ml of its solution which is express in %.
2. Gram per liter: It is defined as the weight of solute dissolve to make 1 liter of solution.
3. Normality: It is defined as the amount of equivalent weight per unit of the volume. It is one of the rarely used indicator.
4. Molarity: it is defined as the amount of the substance or the particles that is formed to make a unit volume of the solution by dissolving them. Here the molar concentration is also known as the molarity as it is dependent upon the concentration.
5. Mole fraction: The mole fraction is another factor or the indicator. It is defined as the unit component of the moles to that the whole component of the moles of the particles.
6. Part per million: We all may have noticed or heard of this word part per million so it describes the concentration of something in the water which is expresses not in 100 but in million. And hence is regarded as part per million.
This all are the indicator that is used to measure the concentration of the substance and is important to exactly measure or determine the strength of the solution.
