The following formulas of substances are given: MgSO4, SrO, NaOH, CO2, CuCl2, H2So4, Ba (OH) 2, H3PO4, Al (OH) 3, NaI Write down the formulas of oxides, acids, bases and salts separately in columns. Give a name to each substance

1. Oxides: SrO – strontium oxide, CO2 – carbon monoxide (iV). Oxides are complex substances, one of which is oxygen. If, in addition to oxygen, a metal is included in the oxide, then this is a basic oxide; if it is not a metal, then the oxide is acidic.

2. Salts: MgSO4 – magnesium sulfate, CuCl2 – copper chloride, NaI – sodium iodide. Salts are complex substances, they consist of a metal and an acidic residue.

3. Bases: NaOH – sodium hydroxide, Ba (OH) 2 – barium hydroxide, Al (OH) 3 – aluminum hydroxide. Bases are complex substances consisting of a metal and one or more hydroxyl groups.

4. Acids: H2SO4 – sulfuric acid, H3PO4 – phosphoric acid. Acids are complex substances, they consist of metal atoms and an acid residue.
