In the following reactions, products (A) and (B), respectively, are:
$\text{NaOH} + \text{Cl}_2 \to \text{(A)} + \text{side products (hot and conc.)}$ $\text{Ca(OH)}_2 + \text{Cl}_2 \to \text{(B)} + \text{side products (dry)}$
(1) $\text{NaClO}_3$ and $\text{Ca(OCl)}_2$
(2) $\text{NaClO}_3$ and $\text{Ca(ClO}_3\text{)}_2$
(3) NaOCl and $\text{Ca(OCl)}_2$
(4) NaOCl and $\text{Ca(ClO}_3\text{)}_2$
Show Answer
Answer: (1)
Solution
$6\text{NaOH} + 3\text{Cl}_2 \to 5\text{NaCl} + \text{NaClO}_3 + 3\text{H}_2\text{O}$. $2\text{Ca(OH)}_2 + \text{Cl}_2 \to \text{Ca(OCl)}_2 + \text{CaCl}_2 + \text{H}_2\text{O}$.
