Question

Sodium hydrogen carbonate (NaHCO,), also known as sodium bicarbonate or "baking soda", can be used to releve add indigestion. Acid Indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI), which the st of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: somach secretes to help digest food. Drinking a glass HCl(ea) + NaHCO(aa)- NaCl(a) H20 co9) The CO 2 gas produced is what makes you burp after drinking the solution. uffering from indigestion can be considered to be 150. ml of a 0.074 M HCI solution. what mass of NaHCO, Suppose the fluid in the stomach of a woman s would she need to ingest to neutralize this much HCI ? Round your answer to 2 significant digits -10

Answer 1

Ans :

Number of mol of HCl = molarity x volume (L)

= 0.074 x 0.150

= 0.0111 mol

So number of mol of NaHCO3 required will also be 0.0111 mol

Mass of NaHCO3 = mol x molar mass

= 0.0111 mol x 84.007 g/mol

= 0.93 g
