กระดาษลิตมัส pH 3 -10 (เหลือง, แดง, น้ำเงิน, ม่วง, ขาว)

Indicator papers without colour scale
For orientation and adjustment of pH values
  These products are simple, completely impregnated indicator papers, which do not allow exact pH determinations, but pH adjustments during special chemical procedures. For this reason, no colour scale is provided with these papers.

Litmus paper blue (Blue to Red)
Quick and easy determination of acidic and alkaline reaction

blue paper

Changes colour from blue to red when conditions change from alkaline to acidic.
Recommended application:
General test for acidic or alkaline reaction: It serves in neutralisation reactions to check whether the change from acid to alkaline or vice versa has taken place. Litmus paper is the bestknown indicator paper.
Chemistry:
Litmus is not a single, chemically defined substance but a natural product containing a mixture of substances. It is extracted from lichen and probably represents the oldest known indicator dye.
