Chemistry

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 (C₆H₅O₇^3-).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?
