• A) \(K = \frac { \left[ \mathrm { Al } ^ { 3 + } \right] \left[ \mathrm { OH } ^ { - } \right] } { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] }\)
• B) \(K = \frac { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] } { \left[ \mathrm { OH } ^ { - } \right] ^ { 4 } }\)
• C) \(K = \frac { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] } { \left[ \mathrm { Al } ^ { 3 + } \right] \left[ \mathrm { OH } ^ { - } \right] }\)
• D) \(K = \frac { \left[ \mathrm { Al } ^ { 3 + } \right] \left[ \mathrm { OH } ^ { - } \right] ^ { 4 } } { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] }\)
• E) \(K = \frac { \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } ^ { - } \right] } { \left[ \mathrm { Al } ^ { 3 + } \right] \left[ \mathrm { OH } ^ { - } \right] ^ { 4 } }\)
