11. Describe the analytical classifications of anions according to their ability to form sparingly soluble compounds and according to their redox properties. Draw up a scheme for the qualitative analysis of SO42-, C2O42-, S2O32-, Cl-, CH3COO- anions in their joint presence. Indicate the group and specific reactions of these anions. Separately note their pharmacopoeial reactions.
