When 9.0ml of arsenius sulphide sol and 1.0ml of 1.0xx10^(-4)M BaCl_(2) are mixed turbidity due to precipitation just appears after 2 hours. The effective ion and its coagulating value are respectively.

Answer»

`Cl^(-),10"m MOL"//L`
`Cl^(-),20"m mol"//L`
`Ba^(2+),10"m mol"//L`
`Ba^(2+),20"m mol"//L`

Solution :CONC. Of `Ba^(2+)=(10^(-4))/(10xx10^(-3))M=10^(-2)M=10"m MOLE"//L`
