Select all that apply.

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

Answer 1

it is also

-many OH- ions

-few H+ ions

-large Kb and small Ka

Answer 2

Step-by-step 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
`OH^(-)` 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,
`NaOH \rightarrow Na^(+) + OH^(-)`

so,
`K_(b) = ([Na^(+)][OH^(-)])/(NaOH)`

Therefore, we can see that more is the concentration of hydroxide ions more will be the value of
`K_(b)`.

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

• many OH- ions.

• few H+ ions.

• large Kb and small Ka.
