Evolution of Hydrogen Gas (Zinc + Dilute Acid) | NCERT Activity 1.3 | Class 10 Science | Science Hub

In this video, we explain the Metal + Acid reaction that leads to the formation of Hydrogen Gas, strictly as per NCERT Class 10 Science.

When a metal reacts with a dilute acid, hydrogen gas is released along with a salt. This reaction is an important example of a displacement reaction and is frequently asked in Class 10 board exams.

Through clear AI-powered animation, you will understand:
Why hydrogen gas is produced
How metal displaces hydrogen from acid
The general chemical equation for metal–acid reactions
How to identify hydrogen gas using the pop test
Key exam points and NCERT terminology

General Reaction:
Metal + Dilute Acid → Salt + Hydrogen Gas ↑

This video is useful for:
✔ Class 10 CBSE / NCERT students
✔ Understanding reactions visually
✔ Quick revision before exams

One animation → clear concept → exam ready.
