Question
Predict the effect of adding H2O liquid to the equilibrium reaction 
**Chemical Reaction: Solubility Equilibrium** The equation depicted represents the solubility equilibrium of zinc hydroxide. In this chemical reaction: \[ \text{Zn(OH)}_2(s) \rightleftharpoons \text{Zn}^{2+}(aq) + 2 \text{OH}^-(aq) \] **Explanation:** - **Zn(OH)\(_2\)(s)**: This is solid zinc hydroxide, which is only sparingly soluble in water. - **Zn\(^{2+}\)(aq)**: Zinc ions in aqueous solution that result from the dissolution of zinc hydroxide. - **2 OH\(^-\)(aq)**: Hydroxide ions in aqueous solution that also result from the dissolution process. **Equilibrium Concept:** This equation illustrates a dynamic balance between the undissolved solid zinc hydroxide and its dissolved ions in solution. The double arrow (⇌) indicates that this is a reversible reaction, where the solid can dissolve into ions, and ions can precipitate to form the solid, reaching an equilibrium state.

Step 1: Le-chatalier's principle

Answer:

Le-chatalier's principle states that on changing any parameter of the system that is at equilibrium, it will shift in the direction where effect of that change can get eliminated.
