A) \[{{x}^{3}}\]
B) \[4{{x}^{4}}\]
C) \[{{x}^{4}}\]
D) \[4{{x}^{3}}\]
Correct Answer: B
Solution :
\[KAl{{(S{{O}_{4}})}_{2}}\xrightarrow{{}}\underset{x}{\mathop{{{K}^{+}}}}\,+\underset{x}{\mathop{A{{l}^{3+}}}}\,+\underset{2x}{\mathop{2SO_{4}^{2-}}}\,\] \[{{K}_{sp}}=[{{K}^{+}}][A{{l}^{3+}}]{{[SO_{4}^{2-}]}^{2}}\] \[=(x)(x){{(2x)}^{2}}=4{{x}^{4}}\]You need to login to perform this action.
