Question

cise 4. Strengths of Acids and Conjugate Bas es For the weak acids identified in Exercise 3, in the space below, arrange the conjugate bases in der of increasing strength. Explain why this order was chosen. expain tue oaur HCI, H2COg.tlco.HCzH3Oz ,HCutlso Lewis acids and bases can be recognized by looking at the Lewis dot structure for a material. Electron rich items containing lone pairs and/or a formal negative charge are Lewis bases. Electron poor items with less than an octet around the central atom and/or a formal positive charge are Lewis acids. kExercise 5 Lewis. Acids and Bases Iuic acid or a Lewis base and indicate this by pla

Explanation / Answer

strong acid will have weak conjugate bases

The decreasing strengths of acids are HCl < HC2H3O2 < H2CO3 < HC6H5O < HCO3-  

the conjugate bases of above in increasing strength is

Cl- < C2H3O2^- < HCO3^- < C6H5O^- < CO3^2-
