Osmolarity VS Osmolality

Osmolarity and the Osmolality is the difference term used to express the concentration of the solution. But there is difference between the Osmolarity and Osmolality.

Following are the difference between Osmolarity and Osmolality.

	Osmolarity	Osmolality
Definition	Osmolarity is defined as the  concentration of a solution expressed in terms of osmoles of solute particles.	Osmolality is defined as the concentration of a solution expressed in terms of the total number of solute particles.
Unit	Particles per liter of solution	Particles per kilogram
	mmol/L.	mOsmol/kg.
Factor affect	It depends on the temperature and pressure.	It does not happen on the temperature and Pressure.

Difference between Diffusion and Effusion

Difference between Diffusion and Effusion

Diffusion and effusion both terms defined the movement of the molecule. But the main difference between the diffusion and effusion is the type of the molecule which moved.

Following are the main difference between Diffusion and effusion

Diffusion:

-The movement of the solute from higher concentration to the lower concentration until the equilibrium established.

-Diffusion occurs in gas, liquid and solid particle.

-The diffusion rate depends on the concentration gradient and the amount of surface area available for diffusion. 

-Collision occurs among the molecule 

Effusion:

-The movement of gases from the small hole known as the effusion.

-Effusion occurs in only gaseous molecule.

-Effusion rates both depend on the molar mass of the gas involved, their rates are not equal.

    - There is no any Collision occur among the molecule

Similarities between Diffusion and Osmosis

Diffusion and Osmosis are the process in both the movement of the solvent is occurring. Diffusion and osmosis both process have so many similarities

Following are the similarities between the Diffusion and Osmosis.

-  Diffusion and osmosis both processes depend on the concentration of the solution.

-  Diffusion and Osmosis in both processes movement of the solvent happens.

-  Diffusion and Osmosis in both solvents move from high concentration of solute to the lower concentration of the solvent.

-  In Diffusion and osmosis, the movement of solvent occurs until the concentration at both solution equalized.

-  Diffusion and the osmosis both does not require the energy

-  Diffusion and Osmosis both happen in living and nonliving cells.

Advantages and Disadvantages of Reverse Osmosis

Following are Reverse osmosis advantage and disadvantages of reverse Osmosis.

Advantages of reverse Osmosis:

- Reverse osmosis softens the water.

-Reverse osmosis is the process removes the dissolved substance from the water and maintain the TDS of the water.

-Reverse osmosis also filters remove many bacteria and pathogens from water.

Bacteria are effectively filtered out from your water.

- No, any chemical treatment is involved in Reverse osmosis. Only filtration and pressure technology is used in Reverse osmosis.

- It requires minimum space for installation.

Disadvantages of reverse Osmosis:

- Wastage of water is happened due to the Reverse osmosis.

- The cost of the system is high    

- Frequently replacement of the membrane used in Reverse osmosis process is required.

- Maintenance needs to be required.

Definition:

-Hypertonic solution is defined as the solution which has higher solute concentration compared to another solution.

-With respect to the osmotic pressure, Hypertonic solution is defined as the have higher osmotic pressure.

-Hypertonic solution is the comparison of the concentration of solute with respect to the other solution.

Hypotonic Solution

Definition:

-Hypotonic solution is defined as solution which has lower solute concentration compared to another solution.

-With respect to the osmotic pressure, Hypotonic solution is defined as the have low osmotic pressure.

-Hypotonic solution is the comparison of the concentration of solute with respect to the other solution.

-The solvent moves into the hypotonic solution. 

Diagram of Hypotonic Solution movement:

Hypotonic Solution movement

Here the B side is the hypotonic (The concentration of the solute is lower) Solution which has low concentration of solute than the Side A.So the solvent molecule move towards the hypotonic solution (B) till the concentration of both sides is equal.

Isotonic Definition

Definition:

-Isotonic solution is defined as the solution which separated by the semi permeable membrane and has same concentration of solute at both side solutions.

-In other words, isotonic solution is defined as the solution that has the same osmolarity.

-Hence the concentration of the solution is equal at the both side of the semi permeable membrane there is no movement of the solvent.

Example:

Isotonic saline solution is given to the patient. The saline solution 0.9% solution chloride. It is the example of the isotonic solution with blood.

Tonicity Definition

Tonicity Definition:

Definition:

-Tonicity is also defined in terms of the osmotic pressure. Tonicity defined as the measure of the osmotic pressure gradient between two solutions.

-In simple language, tonicity is the relative concentration of the solution as compared to another solution which separated by the semi permeable membrane.

Based on the tonicity of the solution it is classified.

There are three types of the solution based on the tonicity

Hypertonic solution

Isotonic solution

Difference between Osmosis and Reverse Osmosis

Difference between Osmosis and Reverse Osmosis

Osmosis and the reverse osmosis are the two phenomenon in which occurs due to the movement of the solvent. The main difference between Osmosis and the reverse osmosis is direction of the movement of the solvent and the pressure applied.

Here, following are the difference between the Osmosis and reverse osmosis.

	Osmosis	Reverse Osmosis
Definition	Osmosis is defined as the movement of a solvent through a semi permeable membrane to lower concentration to higher concentration.	Reverse osmosis is defined as the movement of the solvent through the semi permeable membrane from higher concentration to lower concentration with pressure
movement	The solvent transfer from lower concentration to higher concentration	The solvent transfer from higher concentration to the lower concentration.
Pressure	Pressure is not required	Pressure is required then only reverse osmosis is possible. Applied pressure on higher concentration.
Example	Movement of water in root	Purification of the water.
Process	It naturally occurs.	It is simulated process
Energy	Energy is not required for the process	Energy is required for the process.

        Reverse osmosis definition:

        Definition:

Reverse Osmosis is defined as the movement of solvent in the opposite direction from the osmosis; when pressure is applied.
Pressure is most important factor in reverse osmosis process.

Diagram of Reverse Osmosis:

Reverse Osmosis

-Here is a diagram, the red molecules are the molecule of the solvent while the blue is the solute molecule. And the dotted line is the semipermeable membrane. Pressure is applied to the side where the concentration of the solute is high.

-Due to the applied pressure, thee red solvent molecule passes through the semipermeable membrane toward the other side where the concentration of solute (Blue color molecule) is low. This phenomenon is known as Reverse Osmosis.
