Question:
An azeotropic solution of two liquids has boiling point lower than either of them when it
An azeotropic solution of two liquids has boiling point lower than either of them when it
Updated On: Jun 23, 2023
- shows negative deviation from Raoult- law
- shows no deviation from Raoult's law
- shows positive deviation from Raoult- law
- is saturated
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In case of positive deviation from Raoult's law, the observed vapour pressure is greater than the ideal vapour pressure and boiling point of azeotrope becomes lower than either of pure liquid.

- A region in the form of an equilateral triangle (in x-y plane) of height L has a uniform magnetic field ๐ตโ pointing in the +z-direction. A conducting loop PQR, in the form of an equilateral triangle of the same height ๐ฟ, is placed in the x-y plane with its vertex P at x = 0 in the orientation shown in the figure. At ๐ก = 0, the loop starts entering the region of the magnetic field with a uniform velocity ๐ฃ along the +x-direction. The plane of the loop and its orientation remain unchanged throughout its motion.
Which of the following graph best depicts the variation of the induced emf (E) in the loop as a function of the distance (๐ฅ) starting from ๐ฅ = 0? - Two beads, each with charge q and mass m, are on a horizontal, frictionless, non-conducting, circular hoop of radius R. One of the beads is glued to the hoop at some point, while the other one performs small oscillations about its equilibrium position along the hoop. The square of the angular frequency of the small oscillations is given by [ \(\epsilon_0 \)is the permittivity of free space.]

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
