Which of the following are characteristics of a strong base?

few OH- ions
many OH- ions
few H+ ions
many H+ ions
large Kb and small Ka
large Ka and small Kb
Kb = Ka

Respuesta :

it is also

-many OH- ions

-few H+ ions

-large Kb and small Ka

Explanation:

A strong base is a base that completely dissociates into ions when dissolved in an aqueous solution.

Upon dissociation a base gives hydroxide or [tex]OH^{-}[/tex] ions. This, means that when we dissolve a base in a solution then we will get more number of hydroxide ions.

This will result in decrease in number of hydrogen ions into the solution.

Also, [tex]NaOH \rightarrow Na^{+} + OH^{-}[/tex]

so,     [tex]K_{b} = \frac{[Na^{+}][OH^{-}]}{NaOH}[/tex]

Therefore, we can see that more is the concentration of hydroxide ions more will be the value of [tex]K_{b}[/tex].

Thus, we can conclude that following are the characteristics of a strong base.

  • many OH- ions.
  • few H+ ions.
  • large Kb and small Ka.
