1.	What is [Ag^(+)] ina solution made by dissolving both Ag_(2)CrO_(4) and Ag_(2)C_(2)O_(4) untilsaturation is reachedwith respect to both salt ? [K_(sp) = (Ag_(2)C_(2)O_(4)) = 2 xx 10^(-11), K_(sp) (Ag_(2)CrO_(4)) = 2 xx 10^(-12)]
Answer» `2.80 xx 10^(-4)` `7.6 xx 10^(-5)` `6.63 xx 10^(-6)` `3.52 xx 10^(-4)` Solution :`Ag_(2)CrO_(4)(s) hArr underset(2x+2y)((2AG)^(+)(aq.)) + underset(x)(CrO_(4)^(2-)(aq.))` `Ag_(2)C_(2)underset(2y+2x)(O_(4)(s))hArr2Ag^(+)underset(y)((aq.))+C_(2)O_(4)^(2-)(aq.)` `(K_(sp_(1)))/(K_(sp_(1))) = x/y = (2XX10^(-12))/(2 xx 10^(-11)) rArr = 0.1 ` `2 xx 10^(-11) = (2 x + 2y)^(2).y` `2 xx 10^(-11) = 4.84y^(3)` `y = 1.6 xx 10^(-4)` `:. x = 0.16 xx 10^(-4)` TOTAL`[Ag^(+)] = 2 x + 2y` `= (2 xx 0.16 + 2 xx 1.6) xx 10^(-4) = 3.52 xx 10^(-4)`
