Question

Электролитами являются? N2 ZnSO4 H3PO4 Fe2O3

Answer 1

Только сильный электролит ZnSO4=Zn(2+) + SO4(-2), ну и средней силы H3PO4=3H(+) +PO4(3-)

Answer 2

Electrolytes

Electrolytes are substances that conduct electricity when dissolved in water or melted. They are typically compounds that dissociate into ions in solution. Based on the provided options, the following substances can be classified as electrolytes:

1. N2: Nitrogen gas (N2) is a covalent compound and does not dissociate into ions in solution. Therefore, it is not an electrolyte.

2. ZnSO4: Zinc sulfate (ZnSO4) is an ionic compound that dissociates into zinc ions (Zn2+) and sulfate ions (SO42-) in solution. Therefore, it is an electrolyte.

3. H3PO4: Phosphoric acid (H3PO4) is a weak acid that partially dissociates into hydrogen ions (H+) and phosphate ions (H2PO4-) in solution. Therefore, it is an electrolyte.

4. Fe2O3: Iron(III) oxide (Fe2O3) is a covalent compound and does not dissociate into ions in solution. Therefore, it is not an electrolyte.

To summarize, the electrolytes among the given substances are ZnSO4 and H3PO4.
