WebbThe acid dissociation constant (Ka) is used to differentiate between strong and weak acids. The acid dissociates more as the Ka increases. Strong acids must therefore dissociate more in water. A weak acid, on the other hand, is less likely to ionise and release a hydrogen ion, leading to a less acidic solution. Webb4 feb. 2024 · A large Ka value indicates a strong acid because it means the acid is largely dissociated into its ions. A large Ka value also means the formation of products in the reaction is favored. A small Ka value … WebbThe stronger a base is, the more strongly the formation of its conjugate acid is favored. Calculate the Kb value for the acetate ion (CH3COO-) if the Ka value for acetic acid (CH3COOH) is 1.8 x 10-5. 5.6 x 10-10 Which of the following statements correctly describe the relative strengths of acids and bases, and of conjugate acid-base pairs? calculate percentage of weight loss formula
