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, NaCl, Na2CO3
(b) Na2CO3, NaHCO3, NaCl
(c) Na2CO3, NaCl, NaHCO3
(d) NaCl, NaHCO3, Na2CO3

Correct answer is (d) NaCl, NaHCO3, Na2CO3
Salt A - Nacl
CO2 + H2O + NH3 + \(\underset{(A)}{NaCl}\) \(\longrightarrow\) \(\underset{(B)}{NaHCO_3} + NH_4Cl\)
Salt B - NaHCO3 (baking soda)
\(2 NaHCO_3\,\overset{\triangle}{\longrightarrow}\) \(\underset{(C)}{Na_2CO_3} + CO_2 + H_2O\)
Salt - C = Na2CO3
Salt (A) \(\rightarrow\) NaCl also known as table salt.
Salt (B) \(\rightarrow\) NaHCO3 \(\rightarrow\) Baking soda used in the kitchen for making tasty, crispy pakoras.
Salt (C) \(\rightarrow\) Na2CO3 \(\rightarrow\) used in the manufacturing of glass.
