Question

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?

Answer 1

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

Answer 2

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
