Chapter 6, Problem 13P

Interpretation Introduction

Interpretation:

To select a material that will dissolve the stain.

Concept Introduction:

According to the rule of “like dissolve like”, polar solutes always dissolve polar solvents and non-polar solutes always dissolve non-polar solvent. Here, polarity in chemical species is due to difference in the electronegativity of atoms in the species. For example: Water, ${\text{H}}_{\text{2}}\text{O}$ is polar in nature due to electronegativity difference between hydrogen and oxygen. Also, ${\text{CH}}_{\text{4}}$ is non-polar in nature due to negligible difference between carbon and hydrogen atoms.
