Question

*Calculate the volume, in milliliters, of a 0.205 M solution of NaOH that will completely neutralize each of the following.

A- 2.40 mL of a 0.835 M solution of H2SO4.

B-3.83 mL of a 1.35 M solution of HNO3.

C-6.00 mL of a 3.25 M solution of HCl.

*A 0.210 M NaOH solution is used to titrate 28.0 mL of a solution of H2SO4.
H2SO4(aq)+2NaOH(aq)→H2O(l)+Na2SO4(aq)

A-If 42.6 mL of the NaOH solution is required, what is the molarity of the H2SO4 solution?

*A solution of 0.168 MNaOH is used to titrate 33.0 mL of a solution of H2SO4:   H2SO4(aq)+2NaOH(aq)→2H2O(l)+Na2SO4(aq)

A-If 26.0 mL of the NaOH solution is required to reach the endpoint, what is the molarity of the H2SO4 solution?

*A solution of 0.108 M KOH is used to titrate 15.0 mL of a H2SO4 solution.

A-Write the balanced chemical equation.

B-What is the molarity of the H2SO4 solution if 28.2 mL of the KOH solution is required?

*Determine each of the following for a 0.145 M HBr solution:

A-[H3O+]

B-the balanced chemical equation for the reaction with LiOH
