Question

calculate the oxidation number of sodium zincate

Answer 1

NOC cdsl number of sodium zincate is -6

Answer 2

Answer:

Explanation:

Definition of oxidation state:

The number of electrons that an element's atom in a compound loses or gains is known as the oxidation state.

Definition of oxidation number:

An atom's apparent charge when the electrons are counted in accordance with some arbitrary principles is its oxidation number. The other atoms in the compound affect an atom's oxidation number. For instance, the oxidation number of Cl in KCl is 0.

Formation of sodium zincate(Na2ZnO2):

Sodium cation (Na+) and Zincate anion (ZnO2-2) combine to generate sodium zincate, which has the chemical formula Na2ZnO2. Zincate anion has valency 2 in this instance. However, sodium cation produces sodium aluminate.

Purpose of sodium zincate :

In aqueous solution, sodium zincate is a good conductor of electricity. They discharge ions in an aqueous solution, which conduct electricity. On dilution, sodium zincate releases heat.

The oxidation number of sodium zincate is +2
