A) \[CaC{{O}_{3}}\] is soluble in \[N{{a}_{2}}C{{O}_{3}}\]
B) \[N{{a}_{2}}C{{O}_{3}}\] increases the solubility of fifth group carbonates
C) \[MgC{{O}_{3}}\] will be precipitated out in fifth group
D) None of these
Correct Answer: C
Solution :
As \[N{{a}_{2}}C{{O}_{3}}\] is a strong electrolyte it will cause the precipitation of MgCO3. So (NH4)2CO3 is used as it?s a weaker electrolyte than \[N{{a}_{2}}C{{O}_{3}}.\]You need to login to perform this action.
