On opening a soda bottle the dissolved CO2 comes out and as a result the pH of the soda in the bottle decreases.
Soda water contains carbonic acid which is a weak acid.
When soda is opened and carbon dioxide is released from the weak acid losses compressed gas in it resulting in the decrease in its pH value.
