Sodium hydrogen carbonate , also known as sodium bicarbonate or \"baking soda\",

Question

Sodium hydrogen carbonate , 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 , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved neutralizes excess through this reaction: (aq) (aq) (aq) (l) (g) The 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 of a M solution. What mass of would she need to ingest to neutralize this much ? Be sure your answer has the correct number of significant digits.

Explanation / Answer

data were missing but you will use standard data about the reaction but you also miss is as follows:
NaHCO3 (aq) + HCl (aq) NaCl (aq) + H2O (l) + CO2 (g)
if we have the same amount on both sides balance and after use according to the molarity we will draw the mass in grams:
1 NaHCO3 + 1 HCl NaCl + 1H2O + 1CO2

1 Na 1

2 H 2

1 C 1

3 O 3

1 Cl 1

then we determine the number of grams of sodium bicarbonate with respect to the amount of hydrochloric acid:

NaHCO3= 84,0 g/mol*1 mol= 84g

HCl= 36,46094 g/mol* 1 mol=36,46 g

the balance is in the reason why each 36,46 g of hydrochloric acid will be needed 84g of sodium bicarbonate.
