What happen when zinc scrap is heated with concentrated NaOH solution

1.	What happen when zinc scrap is heated with concentrated NaOH solution ?
Answer» Question⇒ What happen when zinc scrap is heated with CONCENTRATED NaOH solution ? 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) _____________________________ Hope this will help you.....

Answer»

Question⇒ What happen when zinc scrap is heated with CONCENTRATED NaOH solution ?

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)
