Consider the chemical equilibrium of a soap that is present in its aqueous solution. c17h35coona(aq) mc017-1.jpg c17h35coo–(aq) + na+(aq) sodium stearate (soap) stearate ion what will happen if a large quantity of nacl is added to the aqueous solution?

What will  happen  if a large quantity  of NaCl  is added  to the aqueous solution  is  that

the equilibrium will shift  to the left   leading  to the formation  of more  sodium  stearate  soap.

This  is because the addition  of NaCl  will  led  to a increase  of Na^+  ion. An increase  of Na^+ ions will  led  to the shift  of the equilibrium  to the lest which favor  formation of the soap

They are all full and don't need any more electrons in there outer shell.
