Question 1

Choose the expression that gives the molar concentration of a H2SO4(aq) solution if 24.3 mL of a 0.105 M NaOH(aq) solution is required to titrate 60 mL of the acid.
◦ (60 × 24.3)/0.105
◦ (60 × 2)/(24.3 × 0.105)
◦ (24.3 × 0.105)/(60)
◦ (24.3 × 0.105)/(60 × 2)
◦ (60 × 0.105)/(2 × 24.3)

Question 2

Determine the [C2H3O2-] of the following aqueous solution. Initial concentrations are given.  

[HC2H3O2] = 0.250 M, [HI] = 0.120 M Ka (acetic acid)= 1.8 × 10-5

◦ 8.6 × 10-6 M
◦ 3.8 × 10-5 M
◦ 1.8 × 10-5 M
◦ 0.25 M
◦ 0.37 M
