Calcium hydroxide, also known as slaked lime, is an inorganic compound commonly found in the form of a white powder. It has the chemical formula Ca(OH)2 and is mainly used in water treatment, food processing, and in the manufacture of construction materials. Knowing the molar mass of Ca(OH)2 is important in order to determine the amount of the compound in a given sample.

What is a Molar Mass?

Molar mass is the mass in grams of one mole of a substance. A mole is an amount of a substance which contains the same number of particles as there are atoms in 12 grams of the carbon-12 isotope. Molar mass is an important concept in chemistry, as it allows for the calculation of the amount of a substance in a given sample of the material.

How to Calculate the Molar Mass of Ca(OH)2?

The molar mass of Ca(OH)2 is 74.09 g/mol. This is calculated by adding up the molar masses of each atom in the compound. For example, Calcium has a molar mass of 40.08 g/mol, Oxygen has a molar mass of 16.00 g/mol, and Hydrogen has a molar mass of 1.01 g/mol. When added together, these three elements have a molar mass of 74.09 g/mol.

What are the Uses of Ca(OH)2?

Ca(OH)2 is used for many industrial and domestic purposes. It is used in water treatment to remove impurities from drinking water and to make it safe for human consumption. It is also used in food processing as a pH regulator and in the manufacture of construction materials such as cement, concrete, and lime mortar. Ca(OH)2 is also used in the production of paper and leather.

What is the Chemical Formula for Ca(OH)2?

The chemical formula for Ca(OH)2 is Ca(OH)2. This indicates that the compound is composed of one calcium atom, two oxygen atoms, and two hydrogen atoms. It is also referred to as calcium hydroxide, slaked lime, or hydrated lime.

What are the Properties of Ca(OH)2?

Ca(OH)2 is a white powder at room temperature and has a pH of 12.4. It is soluble in water and is slightly alkaline. Ca(OH)2 is an amphoteric compound, meaning it can be both acidic and basic depending on the pH of the solution. It has a melting point of about 58 °C and a boiling point of about 1,395 °C.

How to Store Ca(OH)2?

Ca(OH)2 should be stored in a cool, dry place in a tightly sealed container. It should be kept away from heat and direct sunlight, and should not be exposed to temperatures above 30 °C. Ca(OH)2 should also be kept away from strong acids, as it is reactive and can cause a hazardous reaction.

What are the Safety Precautions of Ca(OH)2?

Ca(OH)2 is an irritant to the eyes, skin, and respiratory system and can cause irritation, redness, and discomfort. When handling Ca(OH)2, protective gloves, safety glasses, and a face mask should be worn. Ca(OH)2 should not be ingested and should be kept away from children and pets.

Conclusion

Ca(OH)2, or calcium hydroxide, is a white powder with the chemical formula of Ca(OH)2. It has a molar mass of 74.09 g/mol and is used for many industrial and domestic purposes, including water treatment, food processing, and in the manufacture of construction materials. Ca(OH)2 should be stored in a cool, dry place and safety precautions should always be taken when handling the material.
