How to Determine Solubility in Water of Organic Compounds
One physical property that has links to intermolecular forces is solubility. Acids and amines are more soluble than nonpolar compounds due to H-bonding. Solubility Of Organic Compounds Video Khan Academy To verify that a compound has dissolved add 5 HCl to the NaOH mixture until the solution is acidic to pH paper. . But depending upon the type of bond involved organic compounds may be soluble or not. Look for a precipitate indicating that the water-soluble salt has converted back into the water-insoluble compound. That is polar compounds usually are soluble in water and non-polar compounds are not soluble in water. From this exercise you should learn which functional groups enhance water-solubility and how the size and shape of the organic compound influences water-solubility. If hydrophillic region is stronger than hydrophobic region molecule is soluble. Structure determines the lipophilicity. However bec...
