Răspuns:
M,NaOH=40g/mol
M,Al(OH)3=78g/mol
ecuatia reactiei este
6x40g.........................................2x78g
Al2(SO4)3 + 6NaOH -----> 3Na2SO4 + 2Al(OH)3
240g.........................................x
x=156g Al(OH)3
Explicație:
NaOH=40g/moli
Al(OH)3 =78g/moli
___________________________
6•40g________2•78g
Al(SO4)3+6NaOH_______3NaSO4+2Al(OH)3
240________x=156gAl(OH)3
