Looking up compound solubilityTo look up a compound's solubility enter its chemical formula or name and click 'Lookup'. In chemical formula you may use:
- Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
- Functional groups: D, T, Ph, Me, Et, Bu, AcAc, For, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
- parenthesis () or brackets [].
- Common compound names.
Examples of compounds with solubility data: H2O, NaCl, CaCO3, NH3, HCl, H2SO4, AgCl, BaSO4, Glucose, Ethanol, Benzoic acid, Cholesterol, water, ammonia, glucose, ethanol.
Compound solubility lookup provides water solubility data for chemical compounds.Solubility Classification
Solubility is classified using the following ranges (g/L):
- Very soluble: ≥ 1000 g/L
- Freely soluble: 100 to 1000 g/L
- Soluble: 30 to 100 g/L
- Sparingly soluble: 10 to 30 g/L
- Slightly soluble: 1 to 10 g/L
- Very slightly soluble: 0.1 to 1 g/L
- Practically insoluble: < 0.1 g/L
What is solubility?
Solubility is the ability of a substance to dissolve in a solvent, typically water. It is usually expressed as the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature. Water solubility is particularly important in chemistry, biology, and environmental science. Factors affecting solubility
Several factors influence the solubility of compounds:
- Temperature: Higher temperatures generally increase solubility for most solids
- Pressure: Affects gas solubility according to Henry's law
- Molecular structure: Polar compounds tend to be more soluble in polar solvents
- pH: Can affect the solubility of acids, bases, and salts
- Presence of other ions: Can increase or decrease solubility through common ion effects
