Question

A base has Kb of 2.5 x 10-11. which of the following statements is true?(1 point)

a) this is a concentrated base
b)this base ionizes slightly in a aqueous solution
c)this is a strong base
d)an aqueous solution of this base would be acidic
I'm thinking b. help and i'll give medal. Thank you

Answer 1

I disagree with the answer pick of D. If you have a neutral pH 7 solution and you proceed to add a base even with an relatively insignificantly low Kb your solution would still be more basic then acidic. The answer should be b which is true that the base only ionizes slightly in aqueous solution. This is also truer to the definition of what Kb represents.
