Option (1) is the correct answer.

Chalk is chemically known as calcium carbonate (CaCO3).

Calamine lotion is primarily composed of zinc oxide or zinc carbonate.

Methane is commonly referred to as marsh gas because it is produced in marshes by the anaerobic decomposition of organic matter.

Blue vitriol is the common name for copper(II) sulfate pentahydrate.

Quicklime is the common name for calcium oxide (CaO).

Blue stone is another name for copper sulfate.

Water glass is a common name for sodium silicate.

Slaked lime is the common name for calcium hydroxide, Ca(OH)2. It is produced by adding water to quicklime (calcium oxide).

Oil of vitriol is an archaic name for concentrated sulphuric acid. This name originated from its oily appearance and its production from vitriols.

Silica is the common name for silicon dioxide, SiO2. It is the primary component of sand and quartz.

Soda ash is the common name for anhydrous sodium carbonate, Na2CO3. It is widely used in glass manufacturing and as a water softener.

Blue vitriol is the common name for copper(II) sulphate pentahydrate, CuSO4.5H2O. It is known for its distinct blue crystalline appearance.

Limestone is a sedimentary rock composed primarily of calcium carbonate, CaCO3. It is widely used in construction and as a chemical feedstock.

Gypsum is the common name for calcium sulphate dihydrate, CaSO4.2H2O. It is frequently used in construction materials like plaster of Paris.

Saltpeter (or saltpetre) is the common name for potassium nitrate, KNO3. It has historically been used in gunpowder and fertilizers.

Soda water is water into which carbon dioxide gas has been dissolved under pressure, forming a weak solution of carbonic acid, H2CO3.

Common salt is the name for sodium chloride, NaCl. It is the primary salt found in seawater and is essential for human health.

Smelling salts are typically composed of ammonium carbonate, (NH4)2CO3. When inhaled, the ammonia gas released stimulates the respiratory system.

Epsom salt is the common name for magnesium sulphate heptahydrate, MgSO4.7H2O. It is often used in baths for muscle relaxation.

Baking soda is the common name for sodium bicarbonate, NaHCO3. It is used as a leavening agent in baking.

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite, which are forms of calcium carbonate, CaCO3.

Caustic soda is the common name for sodium hydroxide, NaOH. It is a highly alkaline substance used in many industrial processes.
