Common ways of describing the concentrations of solutions are weight-in-weight, weight-in-volume, volume-in-volume, and molarity. Less commonly used descriptions include normality and molality.

In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. A concentration can be any kind of chemical mixture, but most frequently solutes and solvents in solutions. The molar (amount) concentration has variants such as normal concentration and osmotic concentration.

Methods of Expressing Concentration of Solutions

• Percentage by weight (w / w %)
• Percentage by volume (V / V%)
• Weight by volume (w / v%)
• Mole fraction (x)
• Parts per million (ppm)
• Molarity (M)
• Molality (m)
• Normality (N)

Mass Concentration (kg/m3 or g/L) – mass of solute/volume of solution. Normality (N) – grams active solute/liters of solution. Molality (m) – moles of solute/mass of solvent (not mass of solution!) Mass Percent (%) – mass solute/mass solution x 100% (mass units are the same unit for both solute and solution)

The amount of solute in a given amount of solution or solvent is known as the concentration. The two most common ways of expressing concentration are molarity and molality.

A high concentration of a substance in a solution means that there’s a lot of it relative to the volume: the Great Salt Lake has very few fish because of the high concentration of salt. To say that you have good concentration skills means that you pay attention well.

1. Train your brain. Playing certain types of games can help you get better at concentrating.
2. Get your game on. Brain games may not be the only type of game that can help improve concentration.
3. Improve sleep.
4. Make time for exercise.
5. Spend time in nature.
6. Give meditation a try.
7. Take a break.
8. Listen to music.

About Transcript. A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.

Concentration Synonyms – WordHippo Thesaurus….What is another word for concentration?

Antonyms: dilution, dispersion, distribution. Synonyms: tightness, immersion, assiduity, compactness, absorption, denseness, assiduousness, density, engrossment. concentration(noun)

High concentration means the amount of solute is high in the solution and low concentration means it is low. Amount of solvent is high in low concentration and low in high concentration of solute.

Osmosis can be defined as the spontaneous movement of solvent molecules through a semi-permeable membrane from a lower-concentration solution to a higher-concentration solution.

Water molecules move into and out of the cell at an equal rate, so the cell’s size remains constant. than a cell. This means water concentration is higher inside the cell than outside.

A solution has certain characteristics:

• It is uniform, or homogeneous, throughout the mixture.
• It is stable and doesn’t change over time or settle.
• The solute particles are so small they cannot be separated by filtering.
• The solute and solvent molecules cannot be distinguished by the naked eye.

A solution is a homogeneous mixture of two or more substances. A solution consists of a solute and a solvent. The solute is the substance that is dissolved in the solvent. The amount of solute that can be dissolved in solvent is called its solubility.

Explanation: The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

The particles of solute in a solution cannot be seen by the naked eye. A solution does not allow beams of light to scatter. A solution is stable. The solute from a solution cannot be separated by filtration (or mechanically).

Solutions are homogeneous mixtures containing two or more substances called the solute and solvent. The solute is the substance that dissolves. The solvent is the dissolving medium. When looking at a solution it is impossible to distinguish the solute from the solvent.

Solutions are made up of two parts: a solvent and a solute. Solvent – The component that dissolves the other component is called the solvent. Solute – The component that is dissolved in the solvent is called solute.

Some Examples of the Solutions are Listed Below:-

Pure Solution – Pure sultion means a solution which does not contain dissolved imputities in it.
