Hints
In salt analysis, group V radicals \(\mathrm{(Ba^{2+}, Ca^{2+} ~and ~Sr^{2+} )}\) are precipitated as their carbonates by adding solid \(\mathrm{NH_4Cl}\) and excess of \(\mathrm{NH_4OH}\) solution followed by solid \(\mathrm{(NH_4)_2CO_3}\)
Choose the correct reagent used for the confirmation of \(\mathrm{Ca^{2+}}\) ion from the following:
