Question

consider the chemical equilibrium of a soap that is present in its aqueous solution.

mathrm{c}_{17} mathrm{h}_{35} mathrm{coona}(mathrm{aq}) longleftrightarrow mathrm{c}_{17} mathrm{h}_{35} mathrm{coo}^{-}(mathrm{aq})+mathrm{na}^{+}(mathrm{aq})

what will happen if a large quantity of ( mathrm{nacl} ) is added to the aqueous solution?

the equilibrium will shift to the right, favoring the dissociation of soap in aqueous solution. the equilibrium will be permanently destroyed by the addition of ( mathrm{nacl} ). the equilibrium will shift to the left to such an extent that it leads to the precipitation of solid soap. the equilibrium will not be affected by the addition of ( mathrm{nacl} ) to the solution.

Explanation:

Step1: Le Chatelier's Principle

Según el principio de Le Chatelier, cuando se agrega un producto (en este caso, \(Na^{+}\) del \(NaCl\)), el equilibrio se desplaza hacia la izquierda para reducir la perturbación.

Step2: Efecto en el equilibrio

Al agregar \(NaCl\), la concentración de \(Na^{+}\) aumenta. El equilibrio \(C_{17}H_{35}COONa(aq)
ightleftarrows C_{17}H_{35}COO^{-}(aq) + Na^{+}(aq)\) se desplaza hacia la izquierda (formación del reactivo, el jabón \(C_{17}H_{35}COONa\)). Si la concentración de \(Na^{+}\) es lo suficientemente alta, el jabón puede precipitar.

Answer:

The equilibrium will shift to the left to such an extent that it leads to the precipitation of solid soap.
