What happen when zinc granules are heated with sodium hydroxide solution? Write
equations of the reaction which takes place.
Answers
Answer:
Explanation:
When a base reacts with a metal metal salt in hydrogen gas are formed.
In this reaction metal is zinc & base is Sodium hydroxide.
When sodium hydroxide solution is heated with zinc granules then Sodium zincate and hydrogen gas are formed.
2NaOH(aq)+ Zn(s)----->Na2ZnO2 (aq)+ H2(g)
The salt formed by the reaction between a base and a metal, the metal is present as a part of the Negative Ion .
In the sodium zincate salt (Na2ZnO2) formed by the reaction between Sodium Hydroxide and Zinc metal , the zinc metal is present at a part of a negative ions , zincate ion (ZnO2-² )
All the metals do not react with bases to form salt and hydrogen gas.
_____________________________
The main product formed in this reaction is sodium zincate(Na2ZnO2)
