Question

ZnO (s) + 2 HCl (aq) reaction ??​

Answer 1

AnswEr :

Acids : Materials which have pH value less than 7, and turns blue litmus to red.

Bases : Materials which have pH value grater than 7, and turns red litmus to blue.

• Reaction of Acids and Bases :

When acids and bases react with each other they form a base and water (H2O) is removed as a side product, known as Neutralisation Reaction.

Moving Ahead To question,

$\large \dashrightarrow \tt{ZnO\ +\ 2HCl\ \to\ ZnCl_2\ +\ H_2O}$

Here,

• ZnO is a Base. (Metallic oxides are basic in nature)
• HCl is a acid.

So, neutralisation reaction took place.
