Write one difference between concentration and stability |
|
Answer» Answer: concentration refers to the amount of a substance in a defined space Concentration is USUALLY expressed in terms of mass per unit volume. Solubility is a chemical 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. HENRY LAW:the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid: C=kPgas C=kPgas where C is the solubility of a gas at a fixed temperature in a particular solvent (in units of M or ML gas/L) k is Henry's law CONSTANT (often in units of M/atm) Pgas is the partial pressure of the gas (often in units of atm) |
