HCl(aq)+NaHCO3(aq)→NaCl(aq)+H2O(l)+CO2(g)    The CO2 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 0.075M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this muchHCl? Be sure your answer has the correct number of significant digits.

Human blood has a pH of approximately 7.4 due to the carbonic acid/bicarbonate ion (H2CO3/HCO3−) buffer system. Any pH changes below 6.8 or above 7.8 can lead to death! Carbonic acid dissociates to form water and carbon dioxide in the equilibrium shown below. This process is crucial in respiration. H2CO3 (aq) ⇋ CO2 (g) + H2O pKa1 = 2.77 Carbonic acid dissociates in water to form the bicarbonate ion and the hydroxonium ion by the following equilibrium reaction:H2CO3 (aq) + H2O ⇋ H3O(aq)+ + HCO3− pKa2 = 3.70    (i) If there is a 25% increase in carbonic acid levels as per pKa1, explain how the body would deal with this change.

You want to determine the acid concentration in a can of Sprite and decide to use titration. The chemical reaction that takes place in the titration procedure of a colorless pop or sports drink is represented by the following chemical reaction:   H3C6H5O7 (aq) + 3 NaOH (aq) → Na3C6H5O7 (aq)+ 3 H2O (l)   If you titrate 20.00 mL of Sprite with 5.85 mL of 0.125 M NaOH, what is the concentration (Molarity) of in this wine?

Sodium hydrogen carbonate (NAHCO,), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: 圖 HCl(aq) + NaHCO,(aq) → NaCl(aq) + H,O(1) + CO,(g) ol. 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 0.065 M HCl solution. What mass of NaHCO, would she need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.
