When a person has excess stomach acid, he or she may ingest some sodium bicarbonate. The rationale for doing this is that the so
2 answers:
Answer: Option (a) is the correct answer.
Explanation:
Sodium bicarbonate has molecular formula as . It is basic in nature as it dissociates to give sodium and bicarbonate ions.
When excess of acid is formed in the stomach then it means there is increase in the concentration of hydrogen ions. So, when sodium bicarbonate is ingested then it will neutralize the excess of acid formed in the stomach.
Thus, we can conclude that the rationale for doing this is that the sodium bicarbonate is a base and will neutralize the excess acid.

The volume of water that will be produced from the reaction will be 6.3 mL
<h3>Stoichiometric calculation</h3>From the equation of the reaction:
The mole ratio of hydrogen sulfate to sodium hydroxide is 1:2.
Mole of hydrogen sulfate = 0.50 x 350/1000 = 0.175 moles
Mole of 15 grams sodium hydroxide = 15/40 = 0.375 moles
Thus, hydrogen sulfide is the limiting reagent.
Mole ratio of hydrogen sulfide to water = 1:2.
Equivalent mole of water = 0.175 x 2 = 0.35 moles
Mass of 0.35 moles of water = 0.35 x 18 = 6.3 grams.
1 gram of water = 1 ml.
Thus, 6.3 grams of water will be equivalent to 6.3 mL
