Acid indigestlon Is the burning sensation you get In your stomach when it contains too much hydrochloric acid (HOCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCI through this reaction: HCl(aq) + NaHCO,(aq)→ NaCl(aq)+ H,0(1) + CO,(g) The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 250. mL of a 0.043 M HCl solution. What mass of NaHCO, would she need to ingest to neutralize this much HCl ? Round your answer to 2 significant digits. Explanation Check…
