Ph Indicator Paper

The level of pH is measured with pH paper and will determine if a solution is acidic, alkaline, or neutral. This is done by dipping the pH paper into a solution and observing the change in color of the paper. The paper comes with a color-coded scale with the colors representing certain value

The approximate pH of a solution can be determined by placing a drop of the solution on a piece of indicator paper. Two types of pH paper are commonly used: litmus paper and universal (Alkacid) paper. The type of pH paper used is dependent on the type of measurement and degree of accuracy required.
