Which of the following statements are incorrect?
(i) Dry slaked lime reacts with $$C{l_2}$$ to give calcium chlorate.
(ii) With excess chlorine ammonia forms nitrogen trichloride.
(iii) Sulphur reacts with $$C{l_2}$$ to give $$SC{l_4}.$$
(iv) With hot and cone. $$NaOH,C{l_2}$$ gives sodium chlorate.
A.
(i) and (ii)
B.
(i) and (iii)
C.
(ii) and (iii)
D.
(ii) and (iv)
Answer :
(i) and (iii)
Solution :
If chlorine is passed through dry slaked lime, bleaching powder is produced.
$$\mathop {Ca{{\left( {OH} \right)}_2}}\limits_{{\text{Slaked lime}}} + C{l_2} \to $$ $$\mathop {Ca\left( {OCl} \right)Cl}\limits_{{\text{Bleaching powder}}} + {H_2}O$$
$${S_8} + 4C{l_2} \to \mathop {4{S_2}C{l_2}}\limits_{{\text{Sulphur monochloride}}} $$
