Marks: +1, -0

Ba^{2+} Ca^{2+}

Solution:

Concept:

In classical qualitative analysis of cations,

Ba^{2+}

and

Ca^{2+}

belong to Group V and are precipitated as their carbonates.

Explanation:

The group reagent for Group V is ammonium carbonate,

(NH_4)_2CO_3

, in the presence of

NH_4Cl

and

NH_4OH

Ba^{2+}

reacts to form a white precipitate of

BaCO_3

Ca^{2+}

reacts to form a white precipitate of

CaCO_3

Both cations are thus precipitated as carbonates.

Answer:

Option D: carbonate & carbonate.
