Zinc Oxide 200 g
Zinc Oxide 200 g (Product Code: SCI-681/299) is an analytical reagent grade zinc oxide (ZnO) used to prepare zinc salts and to identify zinc during salt analysis in school and college chemistry labs. Teachers keep the 200 g pack, supplied with an MSDS, as a reference sample for the yellow-when-hot, white-when-cold test that marks zinc oxide. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges and testing laboratories.

What Is Zinc Oxide Used For?
A favourite classroom use is making zinc sulfate crystals. Zinc oxide is added a little at a time to warm dilute sulfuric acid until no more dissolves, the excess is filtered off, and the solution is evaporated and left to crystallise, a clean route to a soluble salt from an insoluble base. The same oxide shows amphoteric behaviour, dissolving in acids and also in sodium hydroxide solution to form a zincate.
For a salt analysis kit, heating a little of the powder in a dry boiling tube turns it yellow, and it becomes white again on cooling; students compare unknowns against this reference. Outside the lab, zinc oxide is familiar as a white pigment and in rubber, ceramics and skin-care products, which helps connect lessons to everyday materials. Use a clean, dry spatula and keep the pack closed between classes.
Supplier
Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies Zinc Oxide 200 g as part of a laboratory chemicals range for educational and testing users; the reagent is sourced rather than produced by the company. For vendor registration, the supplying company can be identified by Importer-Exporter Code AAECJ8618A (DGFT) and GSTIN 06AAECJ8618A1ZT.

Frequently Asked Questions
What is Zinc Oxide 200 g?
Zinc Oxide 200 g (SCI-681/299) is analytical reagent grade zinc oxide, ZnO, supplied in a 200 g pack with an MSDS. Chemistry laboratories use it to prepare zinc salts, demonstrate amphoteric oxides and serve as a known sample in salt analysis.
Why does zinc oxide turn yellow when heated?
Zinc Oxide 200 g turns yellow on strong heating because the crystal loses a tiny amount of oxygen, creating defects that absorb blue light; it becomes white again as it cools. This reversible colour change is a quick identification test for zinc oxide in salt analysis.
Is zinc oxide acidic or basic?
Zinc oxide is amphoteric: Zinc Oxide 200 g reacts with dilute acids to form zinc salts such as zinc sulfate, and with sodium hydroxide solution to form sodium zincate. This dual behaviour makes it a standard example when classes compare metal oxides.
How should Zinc Oxide 200 g be stored?
Store Zinc Oxide 200 g in a closed container in a dry place away from strong acids and alkalis. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Who supplies Zinc Oxide 200 g?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India supplies Zinc Oxide 200 g, product code SCI-681/299, to schools, colleges, testing laboratories, dealers and importers in India and international markets, with an MSDS in every consignment.
Can tender buyers get vendor registration details?
Yes. For Zinc Oxide 200 g and other chemicals, tender and institutional buyers can request the supplying company's registration details, including its GSTIN and Importer-Exporter Code, along with the quotation through the contact page.
