Water and soap are attracted to each other by what type of electrical attraction?
The type of electrical attraction between soap and water
Answer to Problem 16RQ
Soap and water are attracted to each other by ion-dipole type of electrical attractions.
Explanation of Solution
Soap molecule consists of a long hydrophobic non-polar tail and a hydrophilic polar head containing ionic groups. As the major part of the soap molecules has non-polar part, the grime (dirt and grease) on clothes is attracted to the non-polar part of the soap molecules. Polar water molecules are attracted by the strong ion-dipole attractions to the polar part of the soap molecules.
Soap and water are attracted to each other by ion-dipole type of electrical attractions.
Conclusion:
Therefore, ion-dipole type of electrical attractionis present between soap and water molecules.
