Answer 1

Answer:

ZN (s) + NaOH which gives sodium zincate, together with hydrogen gas. The compound sodium zincate, together with hydrogen gas, is formed when zinc reacts with excess sodium hydroxide. Zinc is an example of transition metal which demonstrates mild reactivity.

Step-by-step explanation:

we can say that aluminum hydroxide acts as an acid by accepting electrons coming from the hydroxide ion of sodium hydroxide. So, in general, an amphoteric substance possesses both acidic and basic properties.
