Why Sodium chloride soluble in water but not soluble in Kerosene? |
|
Answer» Ans:Sodium chloride is an ionic molecule. There exists electronegativity difference between Sodium and Chlorine, which gives polarity to the molecule. Thus sodium chloride is polar molecule.Generally polar molecules will soluble in polar solvents and insoluble in non-polar solvents. Non-polar molecules will soluble in non-polar solvents and insoluble in polar solvents.As sodium chloride is polar molecule it will be soluble in polar solvents like water. And insoluble in kerosene (as it is non-polar solvent). |
