A student is running a titration in the laboratory to determine the alkalinity (Total, bicarbonate and carbonate, hydroxide) of a drinking water sample. The initial pH of the sample is 11.6; 0.02N H2SO4 is used as the titrant; and the sample volume subjected to the titration is 100 mL (0.1L). The results of the titrations were as follows: 18.3 (volume of titrant to drop the pH from 11.6 to 8.3) = 10.0 mL; V4.5 (volume of titrant to drop the...

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 (HCI), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) NaHCO3(aq) NaCl(aq)+ H,O)+ Co,(0) 4 The CO, gas produced is what makes you burp after drinking the solution. Suppose...
