Why is the ionic compound nacl (table salt) able to dissolve in a glass of the molecular compound water (h2o)?

Answer;

Ions from the solute have a strong attraction to the polar solvent

Explanation;When sodium is added to water, the sodium ions Na+ are attracted to the oxygen side of the water molecules, while chloride ions Cl- are attracted to the positively charged hydrogen side of water molecule.This causes sodium ion to split in water and dissolve into separate sodium ions and chloride ions. The process can be represented by this equation.

  NaCl(s) --> Na+(aq) + Cl-(aq)

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).
