Please explain me the reactions of clark's process?

Dear Student,

The Reactions involved in Clark's process for removal of temporary hardness of water are :

• $Mg(HC{O}_3{)}_2 + Ca(OH{)}_2 \stackrel{Heat}{\to } MgC{O}_3 + CaC{O}_3 + 2H_{2}O$
• $Ca(HC{O}_3{)}_2 + Ca(OH{)}_2 \stackrel{Heat}{\to } 2CaC{O}_3 + 2H_{2}O$

Hope this information clears your doubts about the topic

Looking forward to hear from you again!!

Regards
