In the Group analysis of cations, \(Ba^{2+}\) & \(Ca^{2+}\) are precipitated respectively as
- A sulphide & sulphide
- B hydroxide & carbonate
- C carbonate & carbonate
- D chromate & sulphide
Answer & Solution
Correct Answer
(C) carbonate & carbonate
Step-by-step Solution
Detailed explanation
To identify \(Ba^{2+} \& Ca^{2+}\) Reagent \((NH_{4})_{2}CO_{3} + NH_{4}Cl\) is used. \(BaCO_{3}\) & \(CaCO_{3}\) are obtained as precipitates.
