Test Paper Books
Product Code : LSK-CL-10079
Test Paper Books (SKU LSK-CL-10079) are booklets of chemically treated indicator paper for quick tests in the chemistry laboratory. They come in seven types: cobalt chloride, lead acetate, blue, neutral and red litmus, pH 1–14 universal, and starch-iodide. A strip touched to a liquid or held in a gas shows the result by a colour change. Science Lab Supplies provides them from Ambala, India, to schools, colleges, laboratories, tender contractors and distributors.

Applications and Experiments for Test Paper Books
The books are used wherever a fast qualitative result is needed: testing acids and bases, checking the pH of solutions and soils, and identifying gases or water in practical work. They support NCERT Class 7 and 10 acids, bases and salts, Class 11–12 qualitative analysis, and B.Sc. laboratory courses.
- Class 7 and 10 science: classifying household substances as acidic, basic or neutral with litmus.
- Class 11–12 salt analysis: lead acetate paper for sulphide and starch-iodide paper for oxidising gases.
- Confirming water as a product of combustion or dehydration with cobalt chloride paper.
Lead acetate and cobalt chloride are toxic compounds. Handle these papers with forceps or gloves under teacher supervision, keep them away from food, and dispose of used strips according to your laboratory rules.
