Question 1

The common constituent in all acid solutions is
◦ H₂

◦ H⁺

◦ OH^–

◦ H₂SO₄

◦ Cl^–

Question 2

The concentration of oxalate ion (C₂O₄^2–) 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^– + 5C₂O₄^2– + 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
