A) \[CaC{{O}_{3}}\]
B) \[Ca{{(OH)}_{2}}\]
C) \[CaC{{l}_{2}}\]
D) \[HCl\]
Correct Answer: B
Solution :
The calcium bicarbonates present in temporary hard water react with lime \[[Ca{{(OH)}_{2}}]\]to form insoluble calcium carbonates which can be easily filtered off. \[Ca{{(HC{{O}_{3}})}_{2}}+Ca{{(OH)}_{2}}\xrightarrow{{}}2CaC{{O}_{3}}\downarrow \] \[+2{{H}_{2}}O\]You need to login to perform this action.
