Lime Water
Lime Water (Product Code: SCL392/0106) is a clear calcium hydroxide solution, listed as an analytical reagent, used to detect carbon dioxide in respiration, fermentation and exhaled-air experiments in biology and general science classes. It turns milky when the gas is bubbled through it, and each 500 ml pack comes with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside the plant biology lab equipment used in respiration studies.

What Is Lime Water Used For?
The best-known demonstration compares inhaled and exhaled air: two tubes of lime water are connected so that a student breathes in through one and out through the other, and only the exhaled-air tube turns milky. The same test appears in experiments on germinating seeds, respiring plant material kept in the dark and yeast fermenting sugar, where the gas given off is led through lime water to prove it is carbon dioxide. These experiments are standard in any biology experiment kit students use from middle school onward.
Lime water reacts slowly with carbon dioxide in the air, so keep the bottle firmly stoppered and pour out only what the lesson needs. Check that the stock is clear before class, since a stale, cloudy solution gives misleading results. When blowing through tubes, students should breathe out gently and never suck liquid back towards the mouth.
Supplier
Lime Water is supplied by Jain Scientific Equipments Private Limited, which operates under the ScienceLab brand from Ambala, Haryana, India. The company supplies consumable reagents together with respiration apparatus and glassware, so institutions can source a complete practical from one vendor. Read more in our company profile.

Frequently Asked Questions
Why does Lime Water turn milky with carbon dioxide?
Lime Water turns milky because carbon dioxide reacts with the dissolved calcium hydroxide to form calcium carbonate. Calcium carbonate is insoluble, so it appears as a fine white suspension that students can see clearly against a dark background.
Why did the milkiness in Lime Water disappear when we kept bubbling gas?
With excess carbon dioxide, the calcium carbonate in Lime Water converts to soluble calcium hydrogen carbonate and the liquid clears again. Stop bubbling as soon as the milkiness appears if you only need a positive result.
The Lime Water stock looks slightly cloudy. Can it still be used?
Slight cloudiness in Lime Water usually means it has absorbed carbon dioxide from the air. Let it settle or filter off the clear liquid, keep the bottle closed, and check it with exhaled air before the class if in doubt.
What does one pack of Lime Water contain?
One pack of Lime Water contains 500 ml of solution listed as analytical reagent, supplied with its MSDS. Pour out only what each lesson needs so the remaining stock is exposed to air as little as possible.
How long does Lime Water keep?
The shelf life of Lime Water depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep it firmly stoppered, because contact with air slowly turns it cloudy.
Is Lime Water safe for student use?
Lime Water can be used by students with basic care: it is an alkaline solution that can irritate eyes and skin, so goggles should be worn and splashes washed off. When blowing through tubes, students must never suck liquid back.
Who supplies Lime Water?
Lime Water is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. Schools, colleges and distributors in India and international markets can request it with code SCL392/0106 alongside respiration kits and test tubes.
