6. In acidic soils, dissolved Al3+ undergoes a complex formation reaction with S0,2- to form (AISO*“). The equilibrium constant at 25°C for the reaction Al3* (ag) + SO2²- (ag) = AISO*(ag) is 1585. What is AG° for this reaction? How does this value compare with AG° for the reaction Al3+ (ag) + F- (ag) = AlIF2* (ag), for which K = 107 at 25°C? Which is the better ligand to use to trap Al3+ from the soil?

6. In acidic soils, dissolved Al3+ undergoes a complex formation reaction with SO22- to form [AISO*). The equilibrium constant at 25°C for the reaction Al3+ (ag) + SO42- (ag) = AISO**(ag) is 1585. What is AG° for this reaction? How does this value compare with AG° for the reaction Al3+ (ag) + F- (ag) AIF2* (ag), for which K = 107 at 25°C? Which is the better ligand to use to trap Al3+ from the soil?
