Answer:
- Add more zinc hydroxide.
- Increase the temperature.
Explanation:
Hello,
Based on the given chemical reaction at equilibrium:
![Z n ( O H )_ 2 ( s ) \rightleftharpoons Z n ^{2 +} ( a q ) + 2 O H ^- ( a q )](https://tex.z-dn.net/?f=Z%20n%20%28%20O%20H%20%29_%202%20%28%20s%20%29%20%5Crightleftharpoons%20Z%20n%20%5E%7B2%20%2B%7D%20%28%20a%20q%20%29%20%2B%202%20O%20H%20%5E-%20%28%20a%20q%20%29)
Thus, by considering the Le Chatelier's principle, increasing the zinc hydroxide solubility, it means favor the direct reaction, could be attained by:
- Adding more zinc hydroxide as the addition of products favor the formation of products.
- As the reaction is endothermic, the energy is considered as a reactant, therefore, increasing the temperature the direct reaction is favored.
Best regards.
