Iodine Solution N/10
Iodine Solution N/10 (Product Code: SCL-871/178) is a decinormal (0.1 N) iodine solution used as the titrant in iodimetric and iodine–thiosulphate titrations in college and senior secondary chemistry labs. Supplied ready-made in a 500 ml analytical reagent bottle with an MSDS, it spares staff from weighing out volatile iodine crystals and fits neatly into a volumetric analysis kit. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is N/10 Iodine Solution Used For?
In an iodimetric titration the solution is run from a burette into the sample until the first permanent blue-black colour with starch appears; vitamin C (ascorbic acid) in juice or tablets is the favourite classroom example because the result links directly to nutrition. In the reverse arrangement, iodine is titrated with sodium thiosulphate and starch is added near the end, once the solution has faded to pale yellow, so that the blue colour disappears sharply.
The solution fits naturally into a titration kit for school and college students working through redox titrations. The same bottle also serves the blue-black starch test in food and enzyme practicals and can supply iodine for the iodoform test.
Iodine attacks rubber and slowly escapes from loosely closed bottles, so use a burette with a glass stopcock and keep the solution tightly stoppered in amber glass away from light and heat. Check its strength against sodium thiosulphate before exact quantitative work. It stains skin and clothing brown; wear gloves, and wipe up spills with a little thiosulphate solution, which decolourises iodine.
Supplier
Iodine Solution N/10 is supplied by Jain Scientific Equipments Private Limited, a Haryana company that trades as ScienceLab from Ambala, India. It sources volumetric solutions and other reagents so that colleges and schools in India and international markets can obtain their titration materials and glassware in one order.

Related Chemistry Lab Products
For accurate iodine titrations, these reagents and glassware work alongside the solution:
- Sodium Thiosulphate (Thio) — the titrant paired with iodine in iodometric titrations
- Starch Powder — for preparing the starch indicator that gives the blue-black end point
- Iodine Flask — a stoppered titration flask that limits iodine loss
- Burette, Class-B, with Glass Key — a glass stopcock that iodine will not attack
- Reagent Bottle Narrow Mouth, Amber Glass — light-protected storage once the solution is decanted

Frequently Asked Questions
Who supplies Iodine Solution N/10 SCL-871/178?
Iodine Solution N/10 (SCL-871/178) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent solution and sends each 500 ml bottle with an MSDS to laboratories in India and international markets.
What does N/10 mean on Iodine Solution N/10?
N/10 means decinormal, or 0.1 normal. Iodine Solution N/10 is therefore at the concentration most practical manuals specify for iodine titrations at senior secondary and undergraduate level, so it can be used directly from the bottle.
Does Iodine Solution N/10 need standardising?
For accurate quantitative results, yes. Titrate Iodine Solution N/10 against standard sodium thiosulphate before use, particularly after the bottle has been opened many times, because iodine gradually escapes from the solution.
Which indicator is used with Iodine Solution N/10?
Freshly prepared starch solution is the indicator used with Iodine Solution N/10. In thiosulphate titrations add it only near the end point; added too early, iodine binds to the starch and the colour change becomes sluggish.
What is the shelf life of Iodine Solution N/10?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Iodine Solution N/10 tightly stoppered in amber glass somewhere cool and dark, and confirm its strength before critical work.
Can Iodine Solution N/10 be used for the starch test in biology?
Yes. Iodine Solution N/10 can be used as it is, or diluted with water, for spotting on food samples and decolourised leaves in the starch test. Label any diluted portion clearly so it is not later mistaken for the titration standard.
