A) \[CaC{{O}_{3}}\]
B) \[Ca{{(HC{{O}_{3}})}_{2}}\]
C) \[Ca{{(OH)}_{2}}\]
D) \[CaO\]
Correct Answer: C
Solution :
\[\underset{(A)}{\mathop{Ca{{(OH)}_{2}}}}\,+N{{a}_{2}}C{{O}_{3}}\to 2NaOH+CaC{{O}_{3}}\] On passing\[C{{O}_{2}}\]to calcium hydroxide solution. It turns milky due to the formation of \[CaC{{O}_{3}}.\] \[Ca{{(OH)}_{2}}+C{{O}_{2}}\to \underset{\text{Milky}}{\mathop{CaC{{O}_{3}}}}\,+{{H}_{2}}O\] Hence, the correct option is [c].You need to login to perform this action.
