Question 1

Lithium metal dissolves in water to yield hydrogen gas and aqueous lithium hydroxide.  What is the final concentration of hydroxide ions when 5.500 g of lithium metal is dropped into 750. mL of water?
◦ 1.06 M
◦ 0.528 M
◦ 2.11 M
◦ 0.792 M
◦ 0.943 M

Question 2

One method of determining the concentration of hydrogen peroxide (H2O2) in a solution is through titration with the iodide ion.  The net ionic equation for this reaction is
         H2O2 + 2I– +2H+→ I2 + 2H2O
A 50.00 mL sample of a hydrogen peroxide solution is found to react completely with 37.12 mL of a 0.1500 M KI solution.  What is the concentration of hydrogen peroxide in the sample?
◦ 5.568 × 10–2 M
◦ 0.2227 M
◦ 0.1010 M
◦ 0.4041 M
◦ 0.1114 M
