It is necessary to determine where is the salt, where is the acid, where is the base, where are the oxides: Fe2O3, SiO2

It is necessary to determine where is the salt, where is the acid, where is the base, where are the oxides: Fe2O3, SiO2, Fe (OH) 3, H2SiO3, NaOH, H3PO4, CuO, Ca (OH) 2, H2SO4, CuSO4, CO2, HNO3, Ca3 (PO4) 2, Al (NO3) 3, HNO2, FeCl3, Na2SiO3.

1. Fe2O3 – iron oxide (oxide).
2. SiO2 – silicon oxide (oxide).
3. Fe (OH) 3 – iron hydroxide (base).
4. H2SiO3 – silicic acid (acid).
5. NaOH – sodium hydroxide (base).
6. H3PO4 – phosphoric acid (acid).
7. CuO – copper oxide (oxide).
8. Ca (OH) 2 – calcium hydroxide (base).
9.H2SO4 – sulfuric acid (acid).
10. CuSO4 – copper sulfate (salt).
11. CO2 – carbon dioxide (oxide).
12. HNO3 – nitric acid (acid).
13. Ca3 (PO4) 2 – calcium phosphate (salt).
14. Al (NO3) 3 – aluminum nitrate (salt).
15. HNO2 – nitrous acid (acid).
16. FeCl3 – ferric chloride (salt).
17. Na2SiO3 – sodium silicate (salt).
