Quicklime is a very common industrial chemical, heavily used in the manufacture of cement, glass, and in agriculture. It is a frequent topic in Class 10 Chemistry.
Common Name: Quicklime.
Chemical Name: Calcium Oxide.
Chemical Formula: CaO.
Formed by: Heating limestone (CaCO₃ → CaO + CO₂).
Reacts with water to form: Slaked Lime (Ca(OH)₂).
When water is added to quicklime, it reacts vigorously, releasing a large amount of heat (highly exothermic reaction) and making a hissing sound. This process forms Slaked Lime.
Equation: CaO(s) + H₂O(l) → Ca(OH)₂(aq) + Heat (Quicklime) + (Water) → (Slaked Lime)
The chemical name of quicklime is Calcium Oxide, and its formula is CaO.
When quicklime (CaO) reacts with water, it forms slaked lime (Calcium Hydroxide, Ca(OH)₂) and releases a lot of heat.
What Is Rancidity? Oxidation and Hydrolysis of Fats Explained
Rancidity is the oxidation or hydrolysis of fats and oils, producing bad smell and taste. Prevented by antioxidants (BHA, BHT), nitrogen flushing, refrigeration, and airtight packaging.
What is a Saturated Solution in Chemistry?
Learn what a saturated solution is in chemistry. Understand solubility, unsaturated vs saturated, and what happens when you heat a saturated mixture.
How is Petroleum Formed? (The Millions of Years Process)
Learn the step-by-step biological and geological process of how petroleum (crude oil) is formed from dead sea organisms over millions of years under extreme heat.
Fajan's Rules — Covalent Bonding in Ionic Compounds
According to Fajan's rules, covalent bonding is favoured by a small, highly charged cation and a large, easily polarisable anion. Full explanation with examples.
Faraday's Second Law of Electrolysis
Learn Faraday's Second Law of Electrolysis. When the same charge passes through different electrolytes, masses deposited are in proportion to their equivalent masses.
