Chlorine reacts with sodium hydroxide under various conditions to give
A
Sodium hypochlorite
B
Sodium chlorate
C
Sodium chloride
D
None of the above
Answer
Sodium chloride
Explanation
Solution
{\underset{\mathrm{Cold, dilute}}{ {Cl_2 + 2NaOH}}−>\underset{\mathrm{sod. hypochlorite }}{ { NaCl + NaCIO + H_2O }} } {\underset{\mathrm{ hot cone }}{ { 3C12 + 6NaOH}}−>\underset{\mathrm{ sod. chlorate}}{ {5NaCl + NaCIO3 + 3H2O }} } So sodium chloride is formed in both cases.
