How do you determine if something is a good solvent?
That is, solutes typically will dissolve best in solvents that have the most molecular similarities: polar solutes will dissolve better in polar solvents, and nonpolar solutes will dissolve better in nonpolar solvents.
How can you determine if a compound will be soluble in a specific solvent?
To predict whether a compound will be soluble in a given solvent, remember the saying, “Like dissolves like.” Highly polar ionic compounds such as salt readily dissolve in polar water, but do not readily dissolve in non-polar solutions such as benzene or chloroform.
What are the characteristics of a solvent?
solvent, substance, ordinarily a liquid, in which other materials dissolve to form a solution. Polar solvents (e.g., water) favour formation of ions; nonpolar ones (e.g., hydrocarbons) do not. Solvents may be predominantly acidic, predominantly basic, amphoteric (both), or aprotic (neither).
What are four characteristics of a good solvent for extraction?
Not toxic, not flammable.
- Immiscible pair of solvents: water and low polarity organic solvents.
- Good solubility of the target compound.
- Poor solubility of impurities.
- Volatility of the extraction solvent.
- Toxicity and safety properties of the extraction solvent.
What is general rule determining which polarities of solids dissolve in which polarity of liquids?
If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve. If the polarities of the solvent and solute are different (one is polar, one is nonpolar), the solute probably won’t dissolve.
How do you choose a solvent for a reaction?
For the specific reaction you mention, here are some criteria you would consider to select a solvent:
- Because this is an oxidation reaction, choose a solvent that cannot be oxidized, known as an aprotic solvent.
- The solvent needs to dissolve the reagents in the reaction: hypochlorite and 4-tert-butylcyclohexanol.

How do you compare solubility?
The relative MOLAR solubility of salts (saturated solution) can be determined by comparing Ksp values. The greater the Ksp the more ions are in solution, hence the greater the molar solubility.
What are three desirable characteristics to look for when selecting a solvent?
An ideal crystallization solvent should be unreactive, inexpensive, and have low toxicity.
Which tells about solvent?
The solvent is the part of a chemical solution present in the greatest percent. Solutes dissolve into solvents. The solvent is the substance that dissolves the solute and the component of a chemical solution present in the greatest amount….Solvent Examples.
