Asolution base differs from a solution of an acid in that the solution of a base

A solution base differs from a solution of an acid in that the solution of a base has lesser hydrogen ion concentration than the solution of an acid. It is known that acids compounds contains hydrogen and produces hydrogen ion in water. A binary acid however is an acid that have two elements, one of the element has a hydrogen attached to it. Examples of binary acids are hydrogen fluoride (HF), hydrogen bromide (HBr) and hydrogen sulfide (H2S). In naming a binary acid, it has two rules; one, as pure compounds and two, as acid solutions.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
