Question 3 • MO-Physical Science A-CR
Consider the chemical equilibrium of a soap that is present in its aqueous solution. C17H35COONa(aq) 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
A
The equilibrium will shift to the right, favoring the dissociation of soap in aqueous solution.B
The equilibrium will shift to the left to such an extent that it leads to the precipitation of solid soap.C
The equilibrium will not be affected by the addition of NaCl to the solution.D
The equilibrium will be permanently destroyed by the addition of NaCl.
