Answer Details
The complex compound formed when aluminum dissolves in aqueous sodium hydroxide is NaAl(OH)4. This is because when aluminum reacts with sodium hydroxide, it forms a complex ion [Al(OH)4]-. This complex ion has a negative charge and combines with a positive ion like Na+ to form the final compound NaAl(OH)4. The other options are not correct because they do not represent the correct combination of aluminum and sodium hydroxide.
