Aqueous calcium nitrate reacts with sodium hydroxide to produce solid calcium hydroxide and aqueous sodium nitrate. Aluminum can react in displacement reactions to form compounds such as aluminum nitrate by replacing less reactive metals like zinc.
The interaction of aqueous calcium nitrate and aluminum metal can be described through various chemical processes. When calcium nitrate in its aqueous form reacts with sodium hydroxide, solid calcium hydroxide and aqueous sodium nitrate are produced:
Ca(NO3)₂ (aq) + 2NaOH(aq) → Ca(OH)₂ (s) + 2NaNO₃ (aq)
Aluminum metal (Al) can also react with substances like water and different acids. In the case of aluminum's interaction with water in a highly alkaline solution, aluminum hydroxide precipitates:

Furthermore, aluminum can displace other metals in a compound. Aluminum, having a +3 charge and being more reactive, can replace zinc in a compound to form aqueous aluminum nitrate:
Al +
→
+ Zn
This demonstrates aluminum's reactivity and the formation of various compounds through displacement reactions.
