How does IMF affect solubility?

How does IMF affect solubility?

Main Idea: “Like dissolves like.” The stronger the intermolecular forces between solute molecule and solvent molecule, the greater the solubility of the solute in the solvent. Between two polar molecules, the molecule with the smaller hydrocarbon portion (or the larger polar portion) is more soluble in water.

How does pressure affect solubility?

The solubility is a measure of the concentration of the dissolved gas particles in the liquid and is a function of the gas pressure. As you increase the pressure of a gas, the collision frequency increases and thus the solubility goes up, as you decrease the pressure, the solubility goes down..

What forces affect solubility?

There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.

How do intermolecular forces affect volatility?

Substances with strong intermolecular forces have lower vapor pressures and are less volatile, while substances with weak intermolecular forces have higher vapor pressures and are more volatile.

What is the effect of increase in pressure on the solubility of a gas in a liquid?

As the partial pressure increases above the liquid, the solubility of the gases in the solution increases and when the partial pressure of the gas above liquid decreases the solubility of the gas in the solution decreases.

When IMF are weak volatility is?

Volatility-The more volatile, the weaker the intermolecular forces. Vapor pressure-The higher the vapor pressure, the weaker the intermolecular forces. The melting point/boiling point is higher in substances that have stronger intermolecular forces. Intermolecular forces are involved in phase changes.

What decreases as Imfs increase?

As the intermolecular attraction increases, • The vapor pressure ( the pressure of the vapor that is in equilibrium with its liquid) decreases • The boiling point ( the temperature at which the vapor pressure becomes equal to the pressure exerted on the surface of the liquid) increases • Surface tension ( the …

What is solubility and concentration?

• Concentration gives the amount of substances in a solution. Solubility is the ability of a substance to dissolve in another substance. • If the solubility of a material is high in a solvent, then its concentration will be high in the solution. Similarly, if the solubility is low, concentration will be low.

What is the intermolecular force of water?

intermolecular forces of water are forces that result from intermolecular hydrogen bonding that exists between the hydrogen atom of one molecule of water and the electronegative atom of oxygen, O of another molecule of water.

What is solubility in experiment?

Solubility experiments in chemistry are learning labs for most middle schoolers. Solubility means a solvent, often water, has the ability to dissolve another substance called a solute, such as sugar for instance.

What is the definition of solubility in chemistry?

Definition of Solubility. Solubility is the ability of a solid, liquid, or gaseous chemical substance (referred to as the solute) to dissolve in solvent (usually a liquid) and form a solution.
