# 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 HCl, 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 woman suffering from indigestion can be considered to be 200.mL of a 0.089M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl? Be sure your answer has the correct number of significant digits.

Sodium hydrogen carbonate NaHCO3, also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion.

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 200.mL of a 0.089HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl? Be sure your answer has the correct number of significant digits.

Step 1

Given,

Volume of HCl = 200 mL = 0.200 L    (1 mL = 0.001 L)

Molarity of HCl = 0.089 M = 0.089 mol/L

Moles of HCl can be calculated as:

Step 2

The balanced neutralization reaction of HCl and NaHCO3 is:

HCl (aq) + NaHCO3 (aq) → NaCl (aq) + H2O (l) + CO2 (g)

From the reaction it is evident that:

Step 3

Grams of NaHCO3 can be cal...
