미정계수법. Fe2(SO4)3 + NH3 + H2O → Fe(OH)3 + (NH4)2SO4

미정계수법. Fe2(SO4)3 + NH3 + H2O → Fe(OH)3 + (NH4)2SO4

aFe2(SO4)3 + bNH3 + cH2O → xFe(OH)3 + y(NH4)2SO4

 

 

Fe: 2a = x ... (1)

S: 3a = y ... (2)

O: 12a + c = 3x + 4y ... (3)

N: b = 2y ... (4)

H: 3b + 2c = 3x + 8y ... (5)

 

 

a = 1 이라 두면,

from (1), x = 2

from (2), y = 3

from (4), b = 6

from (3), 12 + c = 6 + 12 ---> c = 6
