Which statement best describes what makes a base weak?
a base is weak when it forms few ions in water.
a base is weak when only a little of it is dissolved in water.
a base is weak when its concentration is high.
a base is weak when it totally forms ions in water.

a. A base is weak when it forms few ions in water is the correct option.

Explanation: A weak base when dissolved in water it will not dissociate completely into ions. Hence, they are called weak base.  

Example: NH3-Ammonia. CH3NH2-Methylamine is a weak base.  

NH3+H20NH4+ + OH-

here, they will not completely dissociate into ions. Hence, it will be considered as a weak base.

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
