Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or \"baking

Question

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(I) + 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 0.072M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl?

Round your answer to 2 significant digits.

The answer needs to be in grams.

Explanation / Answer

For Neutralisation:

Milimoles of Acid = Milimoles of Baking Soda

Milimoles of HCl acid = 250 x 0.072

Milimoles of HCl acid = 18

Milimoles of NaHCO3 required = 18

Mass of NaHCO3 required = (18/1000) x 84

Mass of NaHCO3 required = 1.57 g
