Example Question #122 : Reaction Types

Which of the following species will not be present in an aqueous solution of ?

Possible Answers:

All of these will be present in the solution

Correct answer:

Explanation:

The hydroxide ion (OH–) is a strong base and therefore would not be present in an acidic solution. Protons, the hydronium ion, and water will all be present in relatively large amounts within the solution. 

Example Question #23 : P H And Poh Of Strong Acids And Bases

Which of the following anions is the strongest base?

Possible Answers:

Correct answer:

Explanation:

Weaker acids dissociate less in water and therefore, reverse reaction is favored in 

. This indicates that the weaker the acid, the stronger its conjugate base.

, and  are all strong acids. Their conjugates are weak bases.

 has the weakest conjugate acid among the all the choices, so it is the strongest base.
