Potassium Hydroxide
Potassium Hydroxide (Product Code: SCI-435/132) is an analytical reagent grade strong alkali, also called caustic potash, used to absorb carbon dioxide in respiration and photosynthesis experiments, make soft soap and prepare alkaline solutions in school and college laboratories. It is packed in 200 g quantities with an MSDS and must be kept sealed, because it draws moisture and carbon dioxide from the air. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which is also a biology lab equipment supplier in India.

What Is Potassium Hydroxide Used For?
Potassium hydroxide solution readily absorbs carbon dioxide, so biology practicals place it inside a respirometer to remove the carbon dioxide released by germinating seeds, letting a coloured liquid index measure oxygen uptake. It is also sealed in a flask with a leaf to show that a leaf deprived of carbon dioxide makes no starch. In chemistry, it saponifies oils and fats to give soft potassium soap, and its solutions serve as strong-alkali titrants and electrolytes.
Dissolving the solid releases a lot of heat and can spatter, so add it slowly to cold water in a borosilicate beaker while stirring, wearing goggles and gloves. Weigh it quickly and replace the lid at once, since it turns damp on standing, and store it away from acids and from metals such as aluminium and zinc.

Frequently Asked Questions
What is Potassium Hydroxide SCI-435/132 used for?
Potassium Hydroxide SCI-435/132 is used to absorb carbon dioxide in respiration and photosynthesis experiments, to make soft soap by saponification and to prepare strong alkaline solutions for titrations. Being analytical reagent grade, it is dependable for both biology and chemistry benches.
How is Potassium Hydroxide different from sodium hydroxide?
Potassium Hydroxide and sodium hydroxide are both strong alkalis, but potassium hydroxide forms softer soaps and is the alkali usually specified for carbon dioxide absorption in respirometers. Choose Potassium Hydroxide SCI-435/132 whenever your method names potassium.
What pack size is Potassium Hydroxide SCI-435/132?
Potassium Hydroxide SCI-435/132 is supplied in a 200 g pack of analytical reagent grade material with an MSDS. State the number of packs needed for your biology and chemistry sections, and we will prepare one combined quotation.
Why must Potassium Hydroxide be kept sealed?
Potassium Hydroxide absorbs water and carbon dioxide from the air, becoming damp and gradually converting to potassium carbonate. Recap Potassium Hydroxide SCI-435/132 immediately after weighing and store it in a dry cabinet so it keeps its strength.
What is the shelf life of Potassium Hydroxide?
The shelf life of Potassium Hydroxide SCI-435/132 depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. A tightly closed container in a dry place helps it stay usable.
What precautions does Potassium Hydroxide need?
Potassium Hydroxide is highly corrosive to skin and eyes, and dissolving it releases heat that can make the solution spit. Wear goggles and gloves, add Potassium Hydroxide SCI-435/132 slowly to cold water, and follow the supplied MSDS for first aid.
Who supplies Potassium Hydroxide SCI-435/132?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India supplies Potassium Hydroxide SCI-435/132 with its MSDS to schools, colleges, laboratories, dealers and importers in India and international markets. Corrosive solids ship under dangerous-goods rules, so include your destination in the enquiry.
