A) Sodium ions interfere with the detection of fifth group radicals
B) Concentration of carbonate ions is very low
C) Sodium will react with acidic radicals
D) Magnesium will be precipitated
Correct Answer: D
Solution :
When \[{{\left( N{{H}_{4}} \right)}_{2}}C{{O}_{3}}\] is used then the concentration of \[CO_{3}^{2-}\] is comparatively low but when \[N{{a}_{2}}C{{O}_{3}}\]is added then concentration of \[CO_{3}^{2-}\] increases so \[M{{g}^{2+}}\]will be precipitated along with other 5th group radicalsYou need to login to perform this action.
