Question

What can be observed when ${\mathrm{CO}}_2$ gas is bubbled into soap solution?

Answer 1

Bubbling of carbon dioxide in soap solution:

• When ${\mathrm{CO}}_2$ (Carbon dioxide) gas is bubbled into a soap solution, we can observe that the soap solution will form bubbles containing ${\mathrm{CO}}_2$ gas.
• Since ${\mathrm{CO}}_2$ gas is higher in density than soap solution, its bubbles will not float on soap solution.

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