Product Description

Turmeric Paper

Turmeric Paper — specification

Made in our own plant in Ambala Cantt, the Turmeric Paper is supplied to colleges, technical institutes and industry for laboratory work, in single units or bulk. Part of our PH Indicator Paper range.

Paper that is yellow from being saturated with turmeric and is used to detect the presence of alkalis, which turn the paper brown, or boric acid, which turns it red-brown. The test paper allows the quick and easy detection of boric acid and borates. It is impregnated with curcumin, the yellow dye extracted from the roots of Curcuma tinctoria (yellow ginger). The paper is dipped into the sample containing hydrochloric acid (pH 1-2). Afterwards it is allowed to dry. In presence of borate the paper turns orange to red. Dipping into conc. sodium hydroxide causes a green-black color. In the absence of borate, sodium hydroxide leads to a brown-red color.
