Answer:
Stomach is a part of digestive system which is resposnibel for the digestion of protein with the help of acid accumulation of enzymes.
Sometimes stomach produces more acid (hydrochloric acid - HCl) and causes acid reflux. To get rid of acid reflux, an acid supplement (anatcid - NaHCO3) is given to neutralise the effect of acid reflux or hydrochloric acid (HCl) accumulation in the stomach.
<u>The equation showing neutralisation of hydrochloric acid (HCl) with acid or anatcid (NaHCO3):</u>
HCl + NaHCO3 => NaCl + H2CO3
