Partially dissociates in aqueous solution.

Vulnerable spot susceptible to failure.

Least reliable element in system.

Vulnerable area susceptible to damage.

Fundamental force, mediates radioactive decay.

Fundamental force, mediates nuclear decay.

A weak base is a base that, upon dissolution in water, does not dissociate completely, so that the resulting aqueous solution contains only a small proportion of hydroxide ions and the concerned basic radical, and a large proportion of undissociated molecules of the base.

Fundamental interaction, causes nuclear decay.

In mathematics, a weak solution (also called a generalized solution) to an ordinary or partial differential equation is a function for which the derivatives may not all exist but which is nonetheless deemed to satisfy the equation in some precisely defined sense.

Subtle indicators of future trends.

Partially dissociates in solution, conductive.
