Equal moles of \[BaC{{l}_{2}}\] and \[Mg{{(Cl{{O}_{4}})}_{2}}\] are present in two different solutions. As increasingly different masses of \[{{K}_{2}}S{{O}_{4}}\] are added lo these solutions in two independent experiments, following graph is obtained. Which of the following can be concluded from this graph? (Ba=137, K=39, Mg=24.3, S=32, O=16, N=14, Cl=35.5)

A) \[BaS{{O}_{4}}\]and\[MgS{{O}_{4}}\], are precipitated in (1) and (2)

B) \[BaS{{O}_{4}}\] and \[KCl{{O}_{4}}\], are precipitated in (1) and (2)

C) \[KCl{{O}_{4}}\] and \[KCl\] are precipitated In (1) and (2)

D) \[KCl\] and \[MgS{{O}_{4}}\]. are precipitated in (1) and (2)
