      LITMUS PAPER

      Acid: red->red and blue->red

      base: red->blue and blue->blue

      neutral: red->red and blue->blue

      cobalt chloride paper goes from blue to pink in the presence of water

      A rhyme to remember it easily:

      Blue to pink (red) acid I think,

      Pink (red) to blue alkaline (base) true.
