Conclusion Litmus paper is an easy and cheap technique for accurately determining the pH of liquids. A good approximation of a solution's pH can be obtained by comparing the color changes in the litmus paper to a standard pH color chart. Litmus paper offers a workable option for routine pH readings in laboratory and field settings, while being less accurate than electronic pH meters. To evaluate litmus paper's benefits and drawbacks, future investigation should look at its application in more complicated matrices or in extremely acidic environments.
