Question 1

The common constituent in all acid solutions is
◦ H2

◦ H+

◦ OH–

◦ H2SO4

◦ Cl–


Question 2

The concentration of oxalate ion (C2O42–) in a sample can be determined by titration with a solution of permanganate ion (MnO4–) of known concentration.  The net ionic equation for this reaction is
         2MnO4– + 5C2O42– + 16H+→ 2Mn2+ + 8H2O + 10CO2
A 30.00 mL sample of an oxalate solution is found to react completely with 21.93 mL of  a 0.1725 M solution of MnO4–.  What is the oxalate ion concentration in the sample?
◦ 0.02914 M
◦ 0.4312 M
◦ 0.1821 M
◦ 0.3152 M
◦ 0.05044 M
