A) Concentration of \[CO_{3}^{2-}\] ions is very low
B) \[N{{a}^{+}}\] ions will interfere with the detection of \[C{{a}^{2+}},B{{a}^{2+}}\] and \[S{{r}^{2+}}\]
C) Sodium will react with acid radicals.
D) Magnesium will be precipitated.
Correct Answer: D
Solution :
\[N{{a}_{2}}C{{O}_{3}}\] is completely dissociated to \[N{{a}^{+}}\] and \[CO_{3}^{2-}\] ions thus giving high concentration of \[CO_{3}^{2-}\] ions which would precipitate \[M{{g}^{2+}}\] as \[MgC{{O}_{3}}\].You need to login to perform this action.
