What is solubility expression?

What is solubility expression?

Solubility is commonly expressed as a concentration; for example, as g of solute per kg of solvent, g per dL (100 mL) of solvent, molarity, molality, mole fraction, etc. As with other equilibrium constants, temperature can affect the numerical value of solubility constant.

What is able to dissolve in a certain solvent?

Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The species that dissolves, the solute, can be a gas, another liquid, or a solid.

How does temperature affect the solubility of drug substances exhibiting endothermic and exothermic process of dissolution?

As temperature increases, the solubility of a solid or liquid can fluctuate depending on whether the dissolution reaction is exothermic or endothermic. Increasing the temperature will therefore increase the solubility of the solute.

What is the effect of temperature on solubility of the solute to the solvent?

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

What are the 3 kinds of solubility?

Based on the concentration of solute dissolves in a solvent, solutes are categorized into highly soluble, sparingly soluble or insoluble.

What are the factors that affect the rate of dissolution?

The rate of dissolving depends on the surface area (solute in solid state), temperature and amount of stirring.

What refers to the ability of solvent to dissolve a solute?

Dissolving power refers to the ability of a solvent to dissolve a certain amount of a solute. Once no more solute can be dissolved in a solvent it is said to be reached to its saturation point.

When does a solvent become a supersaturated solution?

Once no more solute can be dissolved in a solvent it is said to be reached to its saturation point. By changing temperature and pressure of a solution that has reached its saturation point, some more solute can be dissolved and thereby make a supersaturated solution.

How are solid solutions of metals dissolved in metals?

Solid solutions of metals or nonmetals dissolved in metals. Particles in _________ are so small that they never settle out. *They also cannot be removed by filtering. They don’t even scatter light. The ability of a solute to dissolve in a solvent at a certain temperature (and pressure).

What is the law of the solubility of gas?

What law states that at a given temperature the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid? Supersaturated _____ solutions are very unstable
