Question

Why sealed soda water bottle on opening show the evolution of gas with effervescence ?

Answer 1

Answer:

The liquid in the soda bottle is under high pressure. When you open the bottle, the dissolved carbon dioxide is depressurized and wants to rapidly expand. Thus effervescence is seen when a bottle of soda is opened.

Answer 2

$\mathsf{}$ (1) In a sealed soda water bottle equilibrium attend between soluble $\mathsf{CO_{2}}$ gas in water and insoluble in $\mathsf{CO_{2}}$ gas and maintain constant pressure at given temperature

(2) When bottle is open equilibrium disturb pressure on soluble $\mathsf{CO_{2}}$ gas is decreases and its solubility also decreases does gas evaluated with effervescence
