Which of the following is the chemical name of the common salt we use in our kitchen?
Answer and explanation
Correct answer D
Table salt is sodium chloride (NaCl). Calcium carbonate (CaCO3) is a major constituent of chalk and limestone. Calcium chloride (CaCl2) can be used for de-icing or drying. Anhydrous sodium carbonate (Na2CO3) is soda ash, while washing soda is its decahydrate. Ammonium sulphate ((NH4)2SO4) is used as a fertiliser.
Option feedback
Option A
'Calcium Carbonate' (CaCO3) is the chemical compound found in chalk, limestone, and marble, not kitchen table salt.
Option B
'Calcium Chloride' (CaCl2) is an inorganic salt used mainly for de-icing and as a desiccant, not common table salt.
Option C
Anhydrous sodium carbonate is soda ash. Washing soda is sodium carbonate decahydrate.
Option D
Correct. 'Sodium Chloride' (NaCl) is the chemical name of common kitchen/table salt.
Option E
'Ammonium Sulphate' ((NH4)2SO4) is an inorganic salt used primarily as an agricultural soil fertilizer.
