Common Chemical Compounds and Reactions

CCl4 is Carbon tetrachloride, a chemical compound consisting of one carbon atom bonded to four chlorine atoms. The name reflects the 'tetra' (four) chlorine atoms around carbon. Options A, B, and D incorrectly substitute elements or misrepresent the structure.

Na2CO3 is Sodium carbonate, commonly called soda ash or washing soda. The prefix 'tri-' would indicate three carbon atoms, which is incorrect - carbonate (CO3) is a polyatomic ion containing one carbon atom.

Pure for Sure is indeed the tagline of BPCL (Bharat Petroleum Corporation Limited). This tagline emphasizes the purity and quality assurance of BPCL's petroleum products. The other options listed are major oil companies but do not use this specific tagline - IOCL uses 'Energy of India', HPCL uses 'A Fortune Company', and BP has different branding.

Baking soda is the common name for sodium bicarbonate (NaHCO3), a white crystalline compound used in baking as a leavening agent. It releases carbon dioxide when heated or mixed with acid, causing dough to rise. Don't confuse it with baking powder, which contains sodium bicarbonate plus additional ingredients.

Washing soda is chemically known as hydrated sodium carbonate (Na2CO3·10H2O), where 'hydrated' indicates it contains water molecules in its crystal structure. It's different from baking soda (sodium bicarbonate) and is commonly used for cleaning and laundry purposes.

Baking soda's chemical name is sodium bicarbonate (NaHCO3), a white crystalline compound used as a leavening agent in baking. Sodium carbonate is washing soda, while sodium chloride is table salt. The bicarbonate releases CO2 when heated, causing dough to rise.

NaClO3 is named sodium chlorate following IUPAC nomenclature rules. The '-ate' suffix indicates ClO3^-1 (chlorate ion). Option A incorrectly suggests chloric oxide, option B incorrectly uses '-oxide' suffix, and option D incorrectly proposes 'chloro sodiumoxide' which is not standard chemical naming.

Common table salt has the chemical formula NaCl, which consists of sodium and chloride ions. The question specifically asks about salt composition, and chloride is the correct chemical component.

Oleum is fuming sulfuric acid, which is concentrated sulfuric acid dissolved in excess sulfur trioxide (SO3). It's called 'fuming' because it releases SO3 vapors that form white fumes when exposed to moist air. Options A and C are incorrect because oleum is more concentrated than regular concentrated H2SO4 and is certainly not dilute.

Sodium bicarbonate (NaHCO₃) is commonly known as baking soda, widely used in baking as a leavening agent. Washing soda is sodium carbonate (Na₂CO₃), soda ash is sodium carbonate's industrial name, and bitter salt typically refers to magnesium sulfate (Epsom salt).

Sodium bicarbonate (NaHCO3) is commonly known as baking soda. Baking powder is a mixture of baking soda and a dry acid (usually cream of tartar), alum is potassium aluminum sulfate, and cream of tartar is an acidic byproduct of wine fermentation.

Sodium chloride (NaCl) is the chemical name for common table salt. Iodine is sometimes added to salt but is not the salt itself. Potassium chloride is a salt substitute, while sodium bicarbonate is baking soda.

Sodium bicarbonate is baking soda - pure sodium bicarbonate used as a leavening agent. Baking powder contains baking soda plus cream of tartar and starch. Alum is a different compound, and cream of tartar is an acidic ingredient.

Table salt is sodium chloride (NaCl), the common salt used for seasoning and food preservation. Iodine is often added to table salt as a nutritional supplement, but it's not the salt itself. Potassium chloride is a salt substitute, and sodium bicarbonate is baking soda.
