STARCH PAPER: Function: Starch contributes to the stiffness and bonding within a sheet of paper. Cationic starch is added to improve internal bond, tensile strength, and as part of certain retention and drainage programs.

STARCH IODIDE PAPER: This test paper allows the quick and easy detection of strong oxidizers such as nitrite and free chlorine. Potassium iodide starch paper is also used to control diazotization reactions. Nitrite or free chlorine oxidize potassium iodide to form elemental iodine which reacts with starch to a blue-violet complex.

CHLORINE ESTIMATOR PAPER: This test paper allows the quick and easy detection of Chlorine such as nitrite and free chlorine. Chlorine Estimator paper is also used to control diazotization reactions.

PHENOLPHTHALEIN PAPER: Phenolphthalein and the pH Scale. ... In common practice, chemists use litmus paper to measure the pH of a compound; the paper turns red when dipped in acids and blue when dipped in bases. Phenolphthalein works somewhat differently as it is naturally coloruless but turns pink in alkaline solution.

TURMERIC PAPER: Turmeric paper impregnated with turmeric is used as a test for alkalis, which turn it brown, and for boric acid, which turns it reddish-brown.
