what is the effect of soda water on the process of digestion? As it has been seen that after drinking soda the process is increased...I just want to know that what is the chemistry behind this?
Soda, anything carbonated causes bloating, which stretches the stomach. Mechanoreceptors in stomach detect the stretching resulting in parasympathetic innervation to GI smooth muscle. This causes an increase in GI motility.
Due to presence of hydrogen ion in soda water ,H+ ion Concentration in stomach is increasing (common ion effect) it helps in digestion.
