Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the colour change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple. Litmus can also be prepared as an aqueous solution that functions similarly.
