pthh: \(AlCl_3+3NaOH\rightarrow3NaCl+Al\left(OH\right)_3\) (1)
bđ ___0,1______0,32
pư ___0,1______0,3______________0,1
kt____0_______0,02______________0,1
C/m sau pư (1): NaOH dư, AlCl3 hết
\(NaOH+Al\left(OH\right)_3\rightarrow NaAlO_2+2H_2O\) (2)
C/m sau pư 2: NaOH hết, Al(OH)3 dư
\(n_{Al\left(OH\right)_3dư}=0,1-0,02=0,08\left(mol\right)\)
