Study the four drawings below and then decide which best represents an aqueous solution that has (Water molecules are not shown in the diagrams.) a) b) c) d) acid anion Choose ; the strongest acid. the acid with the largest Ka the largest pH. the acid with the strongest conjugate base. Choose Choose \' Choose Check

Solution

1. B (Pic shown represents a strong acid, as it is 100% dissociated in ions H+ and An- )

2.B (Dissociation constant of strongest acid is highest as acid is 100% dissociated)

3.C ( Largest pH means weakest acid, means which is least dissociated, from photo C is least dissociated)

4. C (Strongest conjugate base is formed by weakest acid. If conjugate base is strong, it will force backward reaction and again acid is formed.)
