A) \[5\times {{10}^{-6}}mole/litre\]
B) \[25\times {{10}^{-6}}mole/litre\]
C) \[5\times {{10}^{-12}}mole/litre\]
D) \[25\times {{10}^{-12}}mole/litre\]
Correct Answer: A
Solution :
\[BaS{{O}_{4}}B{{a}^{++}}+S{{O}^{-\,\,\,-}}\] \[s=\sqrt{Ksp}\] \[s=\sqrt{25\times {{10}^{-12}}}\] \[s=5\times {{10}^{-6}}mole/litre\]
