5. Calculate \( \left[ Ag ^{+}\right],\left[ CO _{3}^{2-}\right] \&\left[ CrO _{4}^{2-}\right] \) in a solution saturated with respect to both \( Ag _{2} CO _{3} \& Ag _{2} CrO _{4} \). Given: \( K _{ sp }\left( Ag _{2} CO _{3}\right)=4 \times 10^{-12}: K _{ sp }\left( Ag _{2} CrO _{4}\right)=2.4 \times 10^{-12} \& \frac{1}{4 \sqrt[3]{5}}=0.146 \)
A) \( \left[ Ag ^{+}\right]=2.336 \times 10^{-4} M \)
B) \( \left[ CO _{3}^{2-}\right]=7.3 \times 10^{-5} M \)
C) \( \left[ CrO _{4}^{2-}\right]=4.35 \times 10^{-15} M \)
D) \( 2\left[ Ag ^{+}\right]=\left[ CO _{3}^{2-}\right]+\left[ CrO _{4}^{2-}\right] \)
