Using a pH meter (measures the H ion [H+] concentration in an aqueous solution) is a typical way to determine whether a solution is an acid or a base. On the pH scale (Range = 1-13) 7 is considered Neutral (neither Acid or Base). A solution with a pH <7 are Acids, while those with a pH >7 are Bases.
First is by universal indicator or Phenophtalein or by litmus paper
How by litmus paper-
Take blue litmus paper if the substance changes it color to red then it is acidic. If it doesn't then it is basic.
Take red litmus paper if the substance changes it color to blue then it is basic and if it's color doesn't change then it is acidic.
Litmus will allow you to tell if a solution is a acid or a base.
pH level Check the pH level of the solution with a piece of litmus paper.
base
contains hydroxide ions.
yes it is a acid

An acid or base is never a single element, it is a solution, and a solution that contains H+ OR OH- in it, so oxygen is neither an acid nor base.
An acid solution has a pH under 7.A base solution has a pH over 7.
Buffer solution is a type of solution which contains acid and at the same time a base material. The two components are a weak acid and a conjugate base or a weak base and its conjugate acid.
Oviously a base...
to get a pH of 7(neutral pH) you need to add a base solution to an acid solution and vice versa until you eventually approach a pH of 7
