write an equation for the reaction of Al2O3 with hydroxide ions.

Al2O3 + OH^-1 ----> ?

Al2O3+2NaOH+7H2O=2Na[Al(OH)4(H2O)2]
or melting together
Al2O3+2NaOH=2NaAlO2+H2O

 

[tieu]

Al2O3+2NaOH+7H2O=2Na[Al(OH)4(H2O)2]
or melting together
Al2O3+2NaOH=2NaAlO2+H2O

ummm Na is spectator ion rite?? are u allowed to put that in??

[Al(OH)4(H2O)2]^-1
AlO2^-1
