Question

The chemical prepared by Solvay's process is \(X\). The chemical prepared by Castner-Kellner process is \(Y\). \(X\) and \(Y\) are respectively

• A. \(\mathrm{NaOH,\ NaCl}\)
• B. \(\mathrm{NaNO_3,\ NaOH}\)
• C. \(\mathrm{NaOH,\ Na_2CO_3}\)
• D. \(\mathrm{Na_2CO_3,\ NaOH}\)

Hint:

Remember the important industrial processes: \[ \boxed{ \text{Solvay process}\rightarrow\mathrm{Na_2CO_3} } \] \[ \boxed{ \text{Castner-Kellner process}\rightarrow\mathrm{NaOH} } \]

Answer 1

The Correct Option is D

Step 1: Recall the product of Solvay's process. Solvay's process is the industrial method for manufacturing \[ \boxed{\mathrm{Na_2CO_3}} \] (sodium carbonate). Hence, \[ X=\mathrm{Na_2CO_3}. \]

Step 2: Recall the product of Castner-Kellner process. Castner-Kellner process is used for the manufacture of \[ \boxed{\mathrm{NaOH}} \] (sodium hydroxide) by electrolysis of brine. Hence, \[ Y=\mathrm{NaOH}. \]

Step 3: Write the answer. Therefore, \[ X=\mathrm{Na_2CO_3}, \qquad Y=\mathrm{NaOH}. \] Hence, \[ \boxed{\mathrm{Na_2CO_3,\ NaOH}}. \] Thus, \[ \boxed{(D)} \] is the correct answer.
