A) \[AgBr({{K}_{sp}}=5\times {{10}^{-13}})\]
B) \[AgCl({{K}_{sp}}=1.8\times {{10}^{-10}})\]
C) \[A{{g}_{2}}C{{O}_{3}}({{K}_{sp}}=8\times {{10}^{-12}})\]
D) \[A{{g}_{3}}As{{O}_{4}}({{K}_{sp}}={{10}^{-22}})\]
Correct Answer: A
Solution :
| [a] \[[A{{g}^{+}}]\] required for precipitation of various salts are |
| \[AgBr=7.07\times {{10}^{-8}},AgCl=1.3\times {{10}^{-5}};\] |
| \[A{{g}_{2}}C{{O}_{3}}=1.26\times {{10}^{-4}};A{{g}_{3}}As{{O}_{4}}=1.38\times {{10}^{-6}}\] |
