29) Which statement explains why 10.0 mL of a 0.50 M H2504(aq) solution exactly neutralizes 5.0

mL of a 2.0 M NaOH(aq) solution?

A)

The moles of H(aq) equal the moles of OH(aq).

The moles of H2502(aq) equal the moles of NaOH(aq).

C)

The moles of H2SO4(aq) are greater than the moles of NaOH(aq).

D)

The moles of H(aq) are greater than the moles of OH(aq).

Answer :

10.0 mL, 0.50 M [tex]H_2SO_4[/tex] will completely neutralize 5.0 mL, 2.0 M NaOH because the moles of each reactant balance one another

Mole ratios

According to the equation of the reaction:

[tex]H_2SO_4 + 2NaOH ---- > Na_2SO_4 +2H_2O[/tex]

The mole ratio is 1:2. Thus NaOH must have twice the number of moles of  [tex]H_2SO_4[/tex] for neutralization to take place.

Mole of 10 mL, 0.5 M  [tex]H_2SO_4[/tex] = 0.001 x 0.5 = 0.005 moles

Mole of 5 mL, 2 M NaOH = 0.005 x 2 = 0.01 moles

Thus, the moles of NaOH is greater than that of  [tex]H_2SO_4[/tex].
