Question

What is the minimum mass of sodium bicarbonate that would be required to completely neutralize 100.0 mL of 0.500 M sulfuric acid?

science chemistry

Answer 1

Answer #1

no of moles of H2SO4 = molarity* volume in L

= 0.5*0.1 = 0.05 moles

2NaHCO3(aq) +H2SO4(aq) ---------> Na2SO4(aq) + 2CO2(g) + 2H2O(l)

1 mole of H2SO4 react with 2 moles of NaHCO3

0.05 moles of H2SO4 react with = 2*0.05/1 = 0.1 moles of NaHCO3

mass of NaHCO3 = no of moles * gram molar mass

= 0.1*84 = 8.4g >>>answer

Some sulfuric acid is spilled on a lab bench. You can neutralize the acid by sprinkling sodium bicarbonate on it and then mopping up the resultant solution. The sodium bicarbonate reacts with sulfuric acid as follows: 2NaHCO3(s)+H2SO4(aq)→ Na2SO4(aq)+2H2O(l)+2CO2(g) Sodium bicarbonate is added until the fizzing due to the formation of CO2(g) stops.
