pH strips are used to determine whether a solution is acidic or basic
The pH number determines if the substance is acidic or basic. Numbers 1-6 determine acidic substances, 1 being the most acidic. Numbers 8-14 determine basic substances, 14 being the most basic. 7 is neutral. (:
The pH number will determine if the liquid is acidic or alkaline.
pH
Acidic or basic.
The acidity of a solution. It can either be acidic, or basic.
pH paper will determine if a substance has basic or acidic qualities.
A pH meter
NO3^- can be acidic depending on what the cation is. For example, a solution of ammonium nitrate (NH4NO3) would be acidic. But a solution of sodium nitrate (NaNO3) would be neutral. So, NO3^- cannot exist by itself. It needs a cation, and that will ultimately determine the pH.
Litmus paper can be used to determine if a solution is acidic or basic

Red color in acidic solutions and blue color in basic solutions.
