A bottle of carbonated water, Hold the bottle firmly and open the cap slightly to release carbon dioxide from the bottle, then turn it back and close it., Shake the bottle gently, then repeat the previous steps a few times., Observe the fizzing in the bottle., The decrease in the number of carbon dioxide molecules in the gas leads to bubble formation, and as the pressure falls the solubility of carbon dioxide decreases. As a result, the equilibrium shifts, favouring the decomposition of carbonic acid and the formation of carbon dioxide.
