Question

Salt 'A’ commonly used in food products, is a reactant to produce salt ‘B', used in the

kitchen for making tasty, crispy pakoras. Salt ‘B’ on heating converts into another salt 'C’, which is used in the manufacturing of glass. Salts ‘A', ‘B' and 'C’ respectively are:

A. NaHCO3, NaCI, Na2CO3

B. Na2CO3, NaHCO3, NaCl

C. Na2CO3, NaCl, NaHC3

D. NaCl, NaHCO3, Na2,CO3​

Answer 1

The correct answer is option B.

Salt 'A' used in food products is sodium bicarbonate (NaHCO3), commonly known as baking soda. When it reacts with other ingredients, it produces salt 'B', which is sodium carbonate (Na2CO3). Salt 'B' is used in the kitchen for making crispy pakoras.

Upon heating, salt 'B' (sodium carbonate) converts into salt 'C', which in this case is sodium chloride (NaCl). Sodium chloride is extensively used in the manufacturing of glass.

Therefore, the correct sequence of salts 'A', 'B', and 'C' is: NaHCO3 (sodium bicarbonate), Na2CO3 (sodium carbonate), and NaCl (sodium chloride), which corresponds to option B.
