Mn(NO3)2 -Mn(OH)2-MnO-MnSO4
Mn(NO3)2+2LiOH=Mn(OH)2+LiNO3
t°
Mn(OH)2=MnO+H2O
MnO+SO3=MnSO4
Na3PO4 = 3Na(+) + PO4(-3)
H2SO4 = H(+) + HSO4(-)
HSO4(-) = H(+) + SO4(-2)
H2SO4 = 2H(+) + SO4(-2)
MgSO4 = Mg(+2) + SO4(-2)
Слабый электролит H2S не диссоциирует
Диссоциация процесс обратимый

Мr=Аr(Cu) + Аr(О)=64=16=80
w(Cu)= (n*Ar(Cu)) / (Mr(CuO))
w(Cu)= 1*64 /80 * 100%=80%
w(O)= 100%- 80%= 20%
