Ok don't.call me mam
I don't know correct ans that's y I asked..
Zn + H2SO4= ZnSO4 + H2
this reaction is of dilute ones
May i answer this question
ok
u can
i just know the , Reaction of zinc with both Type of sulphuric acid , But i don't know that which one is correct
If my answer comes to be wrong Then you are a Spam fighter !! you can delete also

Heya.......!!!!!
This question is based on Reaction of Zinc with Sulphuric Acid ( Dilute and Concentrated )
So ,Let's see the Reactions :
● REACTION OF ZINC WITH DILUTE SULPHURIC ACID :
=> Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved.
reaction : Zn + H2SO4 → ZnSO4 + H2
● REACTION OF ZINC WITH CONCENTRATED SULPHURIC ACID :
reaction :
=> Zn +.2H2SO4 → ZnSO4 + 2H2O + SO2
◆CONCLUSION◆ ➡➡ Reaction of Zinc With Dilute Sulphuric Acid is correct way of carrying out Reaction ,
=>> , because Concentrated Sulphuric acid cannot be used for the preparation of H2 gas as in the reaction SO2 is formed instead of H2 .
Hope It Helps You ☺
