Multiple Choice

Which of the following is the chemical equation that describes the dissolution of aluminum hydroxide in an acid?

A) $\mathrm { Al } ( \mathrm { OH } ) _ { 3 } + \mathrm { OH } ^ { - } \rightarrow \left[ \mathrm { Al } ( \mathrm { OH } ) _ { 4 } \right] ^ { - }$
B) $\mathrm { Al } ( \mathrm { OH } ) _ { 3 } + 3 \mathrm { H } ^ { + } \rightarrow \mathrm { Al } ^ { 3 + } + 3 \mathrm { H } _ { 2 } \mathrm { O }$
C) $2 \mathrm { Al } ( \mathrm { OH } ) _ { 3 } + 2 \mathrm { H } ^ { + } \rightarrow 2 \mathrm { Al } _ { 2 } \mathrm { O } _ { 3 } + 2 \mathrm { H } _ { 2 }$
D) $2 \mathrm { Al } ( \mathrm { OH } ) _ { 3 } + 2 \mathrm { OH } ^ { - } \rightarrow \mathrm { Al } _ { 2 } \mathrm { O } _ { 3 } + 4 \mathrm { H } _ { 2 } \mathrm { O }$
E) $\mathrm { Al } ( \mathrm { OH } ) _ { 3 } \rightarrow \mathrm { Al } ^ { 3 + } + 3 \mathrm { OH } ^ { - }$
