Formulas which correspond to salts a) Na (OH), MgCL2, Cu (OH) b) NaHCO3, Mg (OH) Cl2, K2S c) K3PO4, Al2O3, Na3AlO3

Salts are substances that consist of a metal and an acidic residue.

a) NaOH – sodium hydroxide (base), MgCl2 – magnesium chloride (salt), Cu (OH) 2 – copper hydroxide (base);

b) NaHCO3 – sodium bicarbonate (salt), Mg (OH) Cl2 – magnesium hydroxochloride (salt), K2S – potassium sulfide (salt).

c) K3PO4 – potassium orthophosphate (salt), Al2O3 – aluminum oxide (oxide), Na3AlO3 – sodium aluminate (salt).

Answer: b) NaHCO3, Mg (OH) Cl2, K2S – the row includes: acidic salt, basic salt and medium salt.
