Sodium hydrogen carbonate (NaHCO_3), also known as sodium bicarbonate or \"bakin

Question

Sodium hydrogen carbonate (NaHCO_3), also known as sodium bicarbonate or "baking soda-, can be used to relieve add indigestion. Add 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 NaHCO_3 neutralizes excess HCl through this reaction: HCl(aq) + NaHCO_3(aq) - NaCl (aq) + H_2l(l) + CO_2(g) The CO_2, 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 0.06-M HCl solution. What mass of NaHCO_3 would she need to ingest to neutralize this much HCl ? Round your answer to 2 significant digits.

Explanation / Answer

molar mass of NaHCO3 = 84 g.mol

let the mass of salt be x.so, number of moles = x/84

one mole of HCl reacts with one mole of NaHCO3,

so,

x/84 = 0.1*0.067

or x=0.5628 grams

or x=0.56 grams
