Factors affecting solubility

The greater kinetic energy results in greater molecular motion of the gas particles. A soda bottle is an example of where CO2 is bottled under high pressure.

As a result of an increase in pressure, the gases molecules will now be concentrated in a smaller volume. Recycling is used to ensure maximum extraction.

The effects of pressure changes on the solubility of solids and liquids are negligible. In the case of a polar solute and non-polar solvent or vice versait tends to be insoluble or only Factors affecting solubility to a miniscule degree.

As temperature increases, the average kinetic energy of the gas molecules increases. Quantification of solubility Solubility is commonly expressed as a concentration; for example, as g of solute per kg of solvent, g per dL mL of solventmolaritymolalitymole fractionetc.

Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. This explains why it has the most bubbles and creates the most mess and the best sound! Solubility constants are used to describe saturated solutions of ionic compounds of relatively low solubility see solubility equilibrium.


The energy change associated with dissolving is usually given per mole of solute as the enthalpy of solution. If the pot has a cover, go ahead and cover it. Once a solid solute is added to a solvent, the solute particles dissolve in the solvent and this process is known as dissolution.

Stirring only affects how fast the system will reach equilibrium and does not affect the solubility of the solid at all. On this basis, the factors affecting solubility vary on the state of the solute: This process, known as liquid—liquid extractionis an important technique in synthetic chemistry.

An increase in pressure would result in greater partial pressure because the gas is being further compressed. The solubility constant is a special case of an equilibrium constant. The sound that is made when opening a sealed soda bottle or can is the sound of the pressurized gas escaping.

The solute particles leave the surface of the solid and move into the dissolved aqueous phase. Water and oil do not mix, and will form two layers in the cup or jar.

He added tea leaves and sugar in the water then he observed that sugar dissolved in the water but the tea leaves were still there in the water. First, note that the process of dissolving gas in liquid is usually exothermic. Pour small amounts of olive oil and water into the glass at the same time until the jar or glass is half full.

Set the wooden skewer in the solution and let the liquid cool slowly. The intrinsic dissolution rate is defined by the United States Pharmacopeia.Concept: Factors affecting solubility Concept Overview: When considering the solubility of gases in liquids, the pressure of the gas in contact with the liquid is important information.

Factors affecting solubility. ADVERTISEMENT. Temperature. Basically, solubility increases with temperature.

Solubility And Factors Affecting Solubility

It is the case for most of the solvents. The situation is though different for gases. With increase of the temperature they became less soluble in each other and in water, but more soluble in organic solvents.

"The solubility of a solute in a solvent at a particular temperature is the number of grams of the solute necessary to saturate gm of the solvent at that temperature." FACTORS AFFECTING SOLUBILITY.

Factors affecting solubility Solubility is defined for specific phases. For example, the solubility of aragonite and calcite in water are expected to differ, even though they are both polymorphs of calcium carbonate and have the same chemical formula.

Solubility is defined as the upper limit of solute that can be dissolved in a given amount of solvent at equilibrium. In such an equilibrium, Le Chatelier's principle can be used to explain most of the main factors that affect solubility.


Le Ch â telier's principle dictates that the effect of a stress upon a system in chemical equilibrium can be predicted in that. The temperature, the polarity of the solutes and solvent, the pressure, and the molecular size affect solubility. All of these factors play roles in determining which solutes dissolve in which solvents.
