Question

Balance the following half reactions and determine whether they are oxidation or reduction reactions NO_3 = NO_2 Mno_4 = Mn^2+ Fe(OH)3(S) = Fe^2+ The chemistry laboratory returns the following water analysis: pH = 6.3 Na+ = mg/liter K^+ = 0.5mg/liter Mg^2+ = 0.3mg/liter CI^- = 1.5 mg/liter SO^2-_4 = 2mg/liter NO_3^- = 0.5 mg/liter HCO_3^- = 0.9 mg/liter. Is this analysis both complete and accurate? Explain why or why not. 0.01 mol each of acetic acid (HAc) and ammonia (NH_3) are added to a liter of water. List the chemical species and the constraints on the system at equilibrium.
