pH Paper is a high-quality laboratory indicator paper used for the rapid and convenient determination of the pH value of liquids. It helps to identify whether a solution is acidic, neutral, or alkaline by producing a distinct color change when the paper is dipped into the sample solution. The pH paper is specially treated with sensitive indicator chemicals that react with the hydrogen ion concentration of the solution and display different colors corresponding to different pH levels. The resulting color can be compared with the standard pH color chart provided with the product to determine the approximate pH value.
