Identify A, B, C and D in the reactions (I) x Cl ₂+y NaOH A+B+ H ₂ O (l) (Cold, dil) (II) x Cl ₂+y NaOH C + D + H ₂ O (l) (Hot, conc.)

Options

  1. ANaCl , HCl , NaOCl , NaClO ₃
  2. BNaCl , NaOCl , NaCl , NaClO ₃
  3. CNaCl , NaOCl ₃, NaCl , NaOCl
  4. DNaOCl , Na ₂ O , NaOCl , NaO ₂

Correct answer

B. NaCl , NaOCl , NaCl , NaClO ₃

Step-by-step solution

When chlorine reacts with NaOH , different products are formed depending upon the temperature and concentration of NaOH . aligned & Cl ₂+2 NaOH NaCl + NaOCl + H ₂ O & (Cold and dil.) & 3 Cl ₂+6 NaOH 5 NaCl + NaClO ₃+3 H ₂ O & aligned (Hot and conc.) So, A= NaCl , B= NaOCl , C= NaCl , D= NaClO ₃
