The acidity/basicity is evaluated by the pH:
- pH over 7: basic
- pH under 7: acidic
it can become an acid, or it can be come a base

When an acid and a base undergo neutralization, the two substances formed are water and a salt.
A buffered solution is made up of a weak acid and its conjugate base (or a weak base and its conjugate acid). These components work together to maintain the pH of the solution by resisting changes in acidity or basicity when small amounts of acids or bases are added.
A neutralization reaction in aqueous medium produces a salt and water.
You use litmus paper to tell the difference between acid and base because it is convenient. It is easy to transport and store, it is easy to use and it is easy to the the result, which is a clear change in color.

Reactivity and conductivity.
In a double displacement reaction, ions exchange between two compounds to form new compounds. In an acid-base reaction, an acid reacts with a base to form salt and water. Double displacement reactions usually involve two ionic compounds switching partners, whereas acid-base reactions involve the transfer of protons (H+) from the acid to the base.
