Chemical Substances

Here are the details of the given chemical substances:

1. CaO (Calcium Oxide): - Chemical formula: CaO - Common name: Calcium oxide - Other names: Quicklime, burnt lime - Properties: Calcium oxide is a white, caustic, crystalline solid. It is highly reactive with water, producing calcium hydroxide (Ca(OH)2) in an exothermic reaction. - Uses: Calcium oxide is used in various applications, including cement production, soil stabilization, water treatment, and as a flux in metallurgy.

2. KOH (Potassium Hydroxide): - Chemical formula: KOH - Common name: Potassium hydroxide - Other names: Caustic potash - Properties: Potassium hydroxide is a white, deliquescent solid. It is highly soluble in water and forms a strong alkaline solution. - Uses: Potassium hydroxide is used in the production of soaps, detergents, and various chemicals. It is also used in the manufacturing of biodiesel, as a laboratory reagent, and in some industrial processes.

3. FeCl2 (Iron(II) Chloride): - Chemical formula: FeCl2 - Common name: Iron(II) chloride - Properties: Iron(II) chloride is a greenish-white crystalline solid. It is soluble in water and forms a pale green solution. - Uses: Iron(II) chloride is used as a reducing agent, in the synthesis of other iron compounds, and in water treatment processes. It is also used in the production of pigments, dyes, and inks.

4. H2SO4 (Sulfuric Acid): - Chemical formula: H2SO4 - Common name: Sulfuric acid - Properties: Sulfuric acid is a colorless, oily liquid. It is highly corrosive and has a strong acidic nature. - Uses: Sulfuric acid is widely used in various industries, including chemical manufacturing, petroleum refining, and metal processing. It is used in the production of fertilizers, detergents, dyes, and pharmaceuticals. It is also used in laboratory experiments and as a catalyst in some chemical reactions.
