Concept introduction:
The properties of a solution that depends on the number of solute particles present in solution but do not depend on the nature of solute particles are called as colligative properties.
The four colligative properties of solution are vapor-pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
The word, colligative, means binding of particles together.
The osmotic pressure of a solution is given by the expression as follows:
Here,
The conversion of temperature from degree Celsius
The molality of the solution is calculated by the expression as:
Moles of compound can be calculated by the expression:
So, molality can also be calculated by:

- Soap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
