Litmus paper indicates the pH of a solution. Red litmus paper will turn blue in the presence of bases (alkaline solutions). A black color indicates that a chemical reaction is taking place with the litmus dye or paper, and this does not provide any information on pH. The paper may also turn white in the presence of strong bleaching agents such as chlorine or peroxides.
