1. What is Hydrated Lime?

Hydrated Lime, or calcium hydroxide 90%, is a dry, colorless crystalline powdered inorganic compound known traditionally as slacked lime. Its mineral form, portlandite, can be naturally found in various environments such as fumarole deposits but can be produced in laboratories as Industrial Chemical as well.

2. What is Hydrated Lime used for?

Hydrated lime has a variety of the household as well as industrial uses;

  • It is used in a variety of water treatment, construction and industrial applications.
  • It is effectively utilized in rubber manufacturing and marble or granite cutting.
  • It it is employed in the process in steel industries to neutralize impurities in plants where coke is a by-product.
  • As a basic component, it plays a vital role in citric acid purification in chemical manufacturing.
  • It catalyzes particles emanated after combustion in cement plants, coal fire plants, glass industries, and other incendiary plants.
  • It can be formed into architectural lime putty, which is used in construction and restoration applications.
  • Since its toxicity level is low and its basic properties are favorable, it is widely used in the food industry in removing impurities in the manufacture of maple syrup, sugar cane, or other viscous forms of sugar.
  • Its aqueous form is also employed to stabilize the pH of acidic soil for superior plant growth.


3. What is the Chemical Formula of Hydrated Lime?

Hydrated Lime is an inorganic compound that is also known by its chemical name as calcium hydroxide. It is traditionally called slacked lime and its chemical formula is Ca(OH)2 or H2CaO2.


4. Is Hydrated Lime harmful to life?

In moderate and facilitated usage, hydrated lime is safe to use for a variety of purposes. However, in large quantities, it is extremely hazardous and may pose threat to human life. It can cause skin burns, eye damage, or respiratory irritation. Prolonged and unprotected exposure can be fatal.


5. Where is Hydrated Lime found? What does Hydrated Lime looks like?

Hydrated Lime, chemically known as calcium hydroxide is an inorganic compound that can be produced commercially by treating lime with water. It can be produced in the laboratory by combining aqueous calcium chloride and sodium hydroxide solutions. Portlandite, its mineral form, is relatively rare but can be found in volcanic, plutonic, and metamorphic rocks.

Hydrated lime comes in odorless white to beige-colored powder form.

6. What are the hazardous effects of Hydrated Lime?

Recurrent or continuous or unprotected exposure to hydrated lime may result in serious eye damage, skin and respiratory irritation.


7. What precautionary measures should be in handling Hydrated Lime?

Since hydrated lime is sensitive to carbon dioxide, it must be stored in a firmly sealed container in a dry, well-ventilated environment. When handling this chemical, added precautions must be observed such as safe industrial hygiene standards and wearing proper personal protective equipment. In disposing of this chemical, ensure to dispose of the contents/container in an approved waste disposal plant.


8. What will happen if Hydrated Lime is heated?

When heated, hydrated lime loses water and decomposes calcium hydroxide into calcium oxide (CaO) and water (H2O).


9. Is Hydrated Lime soluble compound?

Ca(OH)2 dissolves readily in glycerol and acids, but very slightly in water. It produces a solution that functions as a mild base when dissolved in water to saturation called limewater.

11. How much does Hydrated Lime cost?

Prices are affected by the cost of raw materials used in the manufacturing process of Hydrated Lime. However, our estimated price of Hydrated Lime is at $180.00 per tonne. Free quotation for bulk orders is available upon request.


12. What is PH of Hydrated Lime?

Hydrated Lime is the hydrated oxide of calcium with a variable pH range from 12.4 - 12.6 at 20°C (68°F).


13. Is Hydrated Lime an Electrolyte compound?

Hydrated lime or calcium hydroxide is relatively soluble in water and it will dissociate completely into its ions. Therefore, Ca(OH)2 it is noted to be a strong electrolyte.


14. Can Hydrated Lime go down the drain?

Hydrated lime or calcium hydroxide can pose hazards to human life and the environment. This material should be recycled, or neutralized with diluted hydrochloric acid to a pH of 6-9, before disposal. It has to be kept out of the sewer, drains, and natural waterways.


15. Is Hydrated Lime Acidic or Basic?

When calcium hydroxide, commonly known as slaked lime (with the chemical formula Ca(OH)2), is dissolved in aqueous solutions, it produces hydroxide ions. As a result, this substance is a base. This chemical liberates OH- ions as a result of electrolyte dissociation.


16. What is Hydrated Lime different from Calcium Oxide?

Calcium oxide, commonly known as unslaked lime, comes in a white, caustic, alkaline, crystalline solid at room temperature. But it also comes in white to pale yellow or brown powder. This material is soluble in water and forms calcium hydroxide or hydrated lime but insoluble in methanol, ether, and octanol. It is commonly used in the basic oxygen steelmaking process and small amounts, it can be used in glass production, calcium aluminate cement, and organic chemicals.
