Question

What happens when Zinc Granules are treated with dilute solution of H2SO4 , HCl , HNO3 , NaCl and NaOH , also write the chemical equations if reaction occurs..​

Answer 1

$\large\boxed{\fcolorbox{blue}{white}{!-----Answer-----!}}$

⭕1. dil. H2SO4.Hydrogen gas is evolved.

Reaction:-

⚫Zn(s)+H2SO4(aq) ——> ZnSO4(aq) +H2(g).

-----------

⭕2. dil.HCl. Hydrogen gas is evolved.

Reaction:-

⚫Zn(s) + 2HCl(aq) ——> ZnHCl2(aq)+ H2(g)

-----------

⭕3. dil. HNO3.Nitrous Oxide is evolved Which is colourless.

Reaction:-

⚫4Zn(s)+10HNO3(aq)——> N2O(g) + 5 H2O(L)

------------

⭕4. NaCl sol.. There is no chemical reaction.

------------

⭕5.NaOH sol. Hydrogen gas is evolved..

Reaction:-

⚫Zn(s)+3NaOH(aq) ——> Na2ZnO2(aq)+H2(g)

Na2ZnO2→ Sodium Zincate...☝️☝️☝️
