Question

Why is the ionic compound NaCl (table salt) able to dissolve in a glass of the molecular compound water (H2O)?

Answer 1

I believe that it is C.

Answer 2

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)
