Explicație:
Apa reactioneaza cu oxizii bazici si formeaza baze
H2O + O.B. --------> B
H2O + CaO= Ca(OH)2
var var stins
nestins
Apa react. cu oxizii acizi si form. acizi
H2O + O.A.--------> A
H2O + SO3= H2SO4
90kg xkg
H2O + CaO= Ca(OH)2
18kg 74kg
x= 90 . 74 : 18= 370 kg Ca(OH)2
90kg ykg
H2 O + SO3= H2 SO4
18 kg 98kg
y= 90 .98 : 18=490 kg H2 SO4
M H2O= 2 +16=18----> 18kg/kmoli
MCa(OH)2 = 40 + 2.16 + 2= 74------> 74kg/kmoli
MH2SO4= 2 + 32 + 4.16=98-------> 98kg/kmoli
