Question

What can we observe when ${\mathrm{H}}_2$ gas is bubbled into soap solution?

Answer 1

Bubbling of hydrogen gas in soap solution:

• When ${\mathrm{H}}_2$(Hydrogen) gas is bubbled into a soap solution, we can observe that, it doesn't get dissolved in it but the solution will easily form bubbles containing ${\mathrm{H}}_2$ gas.
• Since ${\mathrm{H}}_2$ gas is lighter in density than soap solution, its bubbles will start to float on soap solution.

Therefore, when ${\mathrm{H}}_2$ gas is bubbled into soap solution we can observe the formation of bubbles containing Hydrogen gas.
