If equal volumes of `BaCI_(2)` and `NaF` solutions are mixed, which of these combination will not give a precipitate? `(K_(sp) of BaF_(2) =1.7 xx 10^(-7))`.

Options

A. `10^(-3)M BaCl_(2)` nd `2 xx 10^(-2) M NaF`
B. `10^(-3)M BaCl_(2)` and `1.5 xx 10^(-2) M NaF`
C. `1.5 xx 10^(-2)M BaCl_(2)` and `10^(-3) M NaF`
D. `2 xx 10^(-2) M BaCl_(2)` and `2 xx 10^(-2) M NaF`

Answer

C

Explanation

For `'C' K_(sp) gt K_(sp)`
