Litmus paper is a crucial supply for any laboratory, and is used in classrooms of all grade levels. These one hundred neutral strips of litmus paper can be used to determine the pH category of a substance. By way of a mixture of dyes extracted from lichens, they tell you whether the substance is acidic or basic. If the substance is a base, the paper will turn blue. If the substance is acidic, the paper will shift its color to red, allowing you to know whether you’re dealing with an acid or a base in your experiments. The paper will also remain the same color in the presence of a neutral substance. A highly useful tool for basic chemistry.
