Solubility would be your answer.

Iam not going to tell you

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

In the question "in a solution of brine  (salt water), what is the  salt? " the correct answer is a solute. a solute is a component of a  solution  dissolved in the solvent.
