Two enterprising chemistry students decide to develop analternative to Alka-Seltzer tablets, replacing the aspirin(acetylsalicylic acid) with vitamin c (ascorbic acid). Thefollowing table shows one of the formulations they tried for a 5 gtablet.
ingredient | formula | Quantity (mg) |
---|
Sodium bicarbonate | NaHCO3 | 1991 |
citric acid | H3C6H5O7 | 886 |
vitamin c | HC6H7O6 | 370 |
inert binder | | 1753 |
TOTAL MASS: | | 5000 |
When the tablet dissolves in water, it \"frizzes\" as thebicarbonate reacts with the citric acid and the vitamin C. Whatmass of NaHCO3 reacts with the vitamin C?
Citric acid is triprotic, and reacts with the base to form thecitrate ino (C6H5O73-).Write the overall ionic reaction for the acidification of theNaHCO3 by the citric acid, giving CO2 as theproduct. Citric acid should be written asH3C6H5O7 in the netionic equation, as weak acids are written in the molecular formeven though they slightly ionize.
What mass of the NaHCO3 reacts with the citricacid?
What is the mass of CO2 released in thisreaction?
THe remaining NaHCO3 is available to neautralizestomach acid. What mass of stomach HCL could be neutralized by onetablet?
