1.	When 200 ml 0.2M NaCl and 200 ml 0.4M BaCl_(2) and 100 ml 0.2 M KCl are mixed. {:("Column-I","Column-II"),("A) molarity of "Na^(+)" ion","P) 0.04 M"),("B) molarity of "Ba^(+2)" ion","Q) 0.08 M"),("C) molarity of "Cl^(-)" ion","R) 0.16 M"),("D) molarity of "K^(+)" ion","S) 0.44 M"):}
Answer» Solution :A) `[Na^(+)]=(200xx0.2)/(200+200+100)=0.08M` B) `[Ba^(+2)]=(200xx0.4)/(500)=0.16M` C) `[Cl^(-)]=(200xx0.2+200xx0.4xx2+100xx0.2)/(500)` = `0.44M` D) `[K^(+)]=(100xx0.2)/(500)=0.04M`
