Question

Accepted Answer

"Conc. of Cl^$-$ = 0.1 M = 10^$-$1 M

Conc. of CrO$_4^{2 - }$ = 0.001 M = 10^$-$3 M

K_sp(AgCl) = [Ag⁺][Cl^$-$]

[Ag⁺]_AgCl = ${{1.7 \times {{10}^{ - 10}}} \over {{{10}^{ - 1}}}} = 1.7 \times {10^{ - 9}}$

${K_{sp}}(A{g_2}Cr{O_4}) = {[A{g^ + }]^2}[CrO_4^{2 - }]$

$$[A{g^ + }] = \sqrt {{{1.9 \times {{10}^{ - 12}}} \over {{{10}^{ - 3}}}}} = \sqrt {19} \times {10^{ - 4}}$$

$\therefore$ AgCl will be precipitate first"

A solution is 0.1 M in Cl^$-$ and 0.001 M in CrO$_4^{2 - }$. Solid AgNO₃ is gradually added to it. Assuming that the addition does not change in volume and K_sp(AgCl) = 1.7 $\times$ 10^$-$10 M² and K_sp(Ag₂CrO₄) = 1.9 $\times$ 10^$-$12 M³.
