- What mass of CaCO3 would be needed to neutralize 7.86 mL of 8.912 M HCl? (Molar mass of CaCO3 is 100.09 g/mol)Which one of the following statements is correct concerning the acetic acid in vinegar and neutralizing capacity of antacid experiments? O Starch can be used as a binder in antacid tablets. O The antacid tablet should be dissolved in a stoichiometric amount of HCI solution. O An antacid tablet is dissolved in H₂O first then titrated with standardized NaOH solution. O One of the active ingredients in most commercial antacid tablets is Ca(OH)2. O The titration flask should be rinsed with vinegar solution before titration with NaOH solution.||| O crosoft O 3 Sodium hydrogen carbonate (NaHCO3), 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 NaHCO3 neutralizes excess HCl through this reaction: 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 man suffering from indigestion can be considered to be 200. mL of a 0.072 M HCl solution. What mass of NaHCO3 would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.
