Slaked Lime

Slaked Lime is a caustic, inflammable, white (or white-and-beige) powder having a crystalline structure. Slaked Lime solutions can cause chemical burns. At high pH values due to a common-ion effect with the hydroxide anion, its solubility drastically decreases. Aqueous solutions of Slaked Lime are called limewater and are medium-strength bases, which react with acids and can attack some metals such as aluminium(amphoteric hydroxide dissolving at high pH), while protecting other metals, such as iron and steel, from corrosion by passivation of their surface.

Slaked Lime is poorly soluble in water, with a retrograde solubility increasing from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. With a solubility product Ksp of 5.02×10−6 at 25 °C. At ambient temperature, Slaked Lime dissolves in water to produce an alkaline solution with a pH of about 12.5.

1.Slaked Lime is used for preparing bleaching powders, hard water softeners and the disinfecting and clarifying agents of tap water , as well as in building industry;

2.Used as rubber and oil industry additives. Used in lubricants for preventing coking, sludge deposition and anti-corrosion. Used as hard water softeners, disinfectants, antacids and so on;

3. Used as analytical reagents, carbon dioxide absorbents, as well as in organic synthesis;

4. Used for making bleaching powder, hard water softener, depilatory, disinfectant, acid stop agent, astringent and various calcium salts;

5. Use for carbon dioxide examination and gas absorption. Used for leather hair removal, insecticide and water treatment.

Wear impervious protective clothing, including boots, gloves, lab coat, apron, or coveralls, to prevent skin contact.

Dust irritates the respiratory tract. Symptoms may include coughing and shortness of breath. It can cause chemical bronchitis. Ingestion may be followed by severe pain, vomiting, diarrhea, and collapse. Corrosive. Skin and eye contact may produce severe irritation and pain.
