In 1 L saturated solution of `AgCl[K_(sp) (AgCl) = 1.6 xx 10^(-10)]` 0.1 mol of CuCl `[K_(sp)(CuCl) = 1.0 xx 10^(-6)]` is added. The resultant concentration of `Ag^(+)` in the solution is `1.6 xx 10^(-x)`. The value of "x" is |

Answer» Correct Answer - 7 `{:(AgCl(s)hArr,"Ag"^(+),+"Cl"^(-),K_(sp)(AgCl) = 1.6 xx 10^(-10)),(,Z,Z+Y,),(CuCl(s) hArr,Cu^(+),+Cl^(-),K_(sp)(CuCl) = 10^(-6)),(,Y,Z+Y,):}` `Z(Z+Y) = 1.6 xx 10^(-10)` `Y(Z+Y) = 10^(-6)` `rArr (Z + Y)^(2) = 1.6 xx 10^(-10) + 10^(-6) rArr (Z + Y)^(2) ~~ 10^(-6)` `rArr Z + Y = 10^(-3) rArr Z(Z + Y) = 1.6 xx 10^(-10)` `rArr Z xx 10^(-3) = 1.6 xx 10^(-10) rArr Z = 1.6 xx 10^(-7)` `rArr 1.6 xx 10^(-x) = 1.6 xx 10^(-7) rArr x = 7`. |
