Answer 2

It is incorrect because sodium phosphate is a compound that has a single composition.

Step-by-step explanation:

Sodium phosphate is a compound and not a mixture. It is made up of sodium and phosphate ions and they exists as just a single compound and not different entities.

The parts of a mixture exists separately and they retain their identities.

• In the compound a sodium phosphate we have 3 atoms, Na, P and Oxygen joined together in a definite grouping.
• The properties of the compound are different from the individual elements that makes them up.
