Acidity/basicity are determined by the pH measurement.
Whether or not it's an acid or a base
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
You can use a pH-paper.
To determine if the property is an Acid the solution must be less than pH 7. and to determine if the property is a Base the solution must be greater than pH 7.
The solution is a base. ( If it turned red, then the solution would be classified as an acid.)
titration is a method by which a solution of known concentration is used to determine the unknown concentration of a second solution. Titration methods are based on reactions that are completed quickly such as the mixing of an acid and base.
it is base
In order to determine whether it is an acid or base you will first have to check the measurements of hydronium. This can found in the pH concentration.
Titration
The simplest way would be to use litmus paper, depending on the color it changes - that indicates whether you're dealing with an acid or a base. Pink/red is an acid, Blue is a base.
