Distribute according to the classification of inorganic compounds: Al (oh) 3, H2SO4, NO

Distribute according to the classification of inorganic compounds: Al (oh) 3, H2SO4, NO, BaO, P2O5, Ni, Mg (OH) 2, CaSO4, H3PO4, NaHSO4, ZnOHCl, KNO3, Li2CO3, Na3 [AlF6], NH4Fe (SO4) 2 , CaHPO4

From the above list, only metal – Ni belongs to simple substances. The rest of the connections are complex.

Oxides:

BaO – basic;

NO – non-salt-forming;

P2O5 is acidic.

Acids:

H2SO4 – strong, dibasic, oxygenated;

H3PO4 – weak, tribasic, oxygenated.

Reasons:

Al (OH) 3, Mg (OH) 2 – insoluble.

Salts:

CaSO4, KNO3, Li2CO3 – medium;

NaHSO4, CaHPO4 – acidic;

ZnOHCl – basic;

Na3 [AlF6] – complex;

NH4Fe (SO4) 2 – double.
