Question

Sodium hydrogen carbonate (NaHCO,), also known as sodium bicarbonate or "baking soda". can be used to relieve acid indigestion. Acd indgestionis the burning sensation you get in your stomach when t contains too much hydrochloric aod (HC) . which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: acid (HCI), which the stomach secretes to help digest food. Drinking a glass HCI(aq) + NaHCO3(aq) → NaCl(aq) + H2O() + co,(9) 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 100. ml of a 0.094 M HCI 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. O Type here to search

Answer 1

1)

moles of HCl = 100 x 0.094 / 1000

                      = 9.4 x 10^-3 mol

moles of HCl = moles of NaHCO3

moles of NaHCO3 = 9.4 x 10^-3 mol

mass of NaHCO3 = 9.4 x 10^-3 x 84

                             = 0.790 g
