Concept explainers
(a)
Interpretation:
Nanoscale diagram for the contents of a beaker containing water and sugar has to be drawn.
Concept introduction:
Like dissolves like principle: ‘Like dissolves like’ principle says that polar compounds including ionic compound should be more soluble in polar solvent. Likewise, non–polar compound should be more soluble in non–polar solvent.
Polar molecule: Polar molecules have large dipole moments.
Non-Polar molecules: Non-polar molecules have bonded atoms with similar electronegativity results to have zero dipole moments.
Solubility: is the quantity of solute (solid, liquid or gas) that will dissolve in a given amount of solvent (solid, liquid or gas) at definite temperature and pressure. Solubility depends on the physical and chemical property of solvent, solute and concentration of the solution.
(b)
Interpretation:
Nanoscale diagram for the contents of a beaker containing Carbon tetrachloride and sugar has to be drawn.
