Example Question #121 : Reaction Types
Would H2SO4 or HNO3 produce a more acidic solution?
HNO3 since it has a higher pKa
H2SO4 since it has a lower pKa
H2SO4 since it has a higher pKa
HNO3 since it has a lower pKa
H2SO4 since it has a lower pKa
Both are strong acids, but H2SO4 is bivalent, realeasing 2 protons for each molecule dissolved in solution. Further, a more acidic solution would have a lower pKa.
Example Question #122 : Reaction Types
Which of the following species will not be present in an aqueous solution of ?
All of these will be present in the solution
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?
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.
