SUMMARY
The reaction between sodium hydroxide (NaOH) and zinc (Zn) results in the formation of zincate, while the reaction between zinc and hydrochloric acid (HCl) produces hydrogen gas (H2). In the NaOH and Zn reaction, the solution may exhibit color changes due to the formation of zincate, which is a consequence of the amphoteric nature of the hydrated zinc ion. In contrast, the Zn and HCl reaction primarily involves the evolution of hydrogen gas without significant color change or deposition. Both reactions involve hydrogen gas evolution, but the products and observable changes differ significantly.
