Question

Which base is the strongest for the given [H+]? 10-9 10-11 10-10 10-12

Answer 1

The answer is 10-12. The strongest base has the lowest concentration of H+
Hope this helped

Answer 2

[H⁺] = 10⁻¹²

It could be the strongest base.

Step-by-step explanation:

The base is considered to be of highest strength if it has least hydrogen ion concentration or high hydroxide ion concentration.

Generally a stronger base gives more hydroxide ion concentration.

the relation between hydrogen ion and hydroxide ion concentration is

[H⁺][OH⁻]= 10⁻¹⁴

[OH⁻] = 10⁻¹⁴ / [H⁺]

a) [H⁺] = 10⁻⁹

[OH-] = 10⁻⁵

b) [H⁺] = 10⁻¹¹

[OH-] = 10⁻³

c) [H⁺] = 10⁻¹⁰

[OH-] = 10⁻⁴

d) [H⁺] = 10⁻¹²

[OH-] = 10⁻²

This the highest concentration of hydroxide ion in the given choices so it could be the strongest base.
