Hβ‚‚SOβ‚„:
m=6.33g M=98g/mol
n = m/M = 6.33g/98g/mol β‰ˆ 0,065mol
NaOH:
m=5.29g M=40g/mol
n = m/M = 5.29g/40g/mol β‰ˆ 0,132mol
2NaOH + Hβ‚‚SOβ‚„ β‡’ Naβ‚‚SOβ‚„ + 2Hβ‚‚O 2mol : 1mol : 1mol 0.132mol : 0.065mol : 0.065mol too much limiting reactant
Limiting reactant is Hβ‚‚SOβ‚„.

The limiting reactant when 6.33 g of H2SO4 reacts with 5.92 g of NaOH is H2SO4, as we need 0.1290 moles of NaOH for the amount of H2SO4 present, and we have more NaOH than required. ;

The limiting reactant when 6.33 g of Hβ‚‚SOβ‚„ reacts with 5.92 g of NaOH is Hβ‚‚SOβ‚„, as it is the reactant that will be consumed first based on the stoichiometric ratios. NaOH is in excess. Therefore, the amount of NaOH present is sufficient for the reaction with Hβ‚‚SOβ‚„.
