The best analysis of Eli’s statement is:
It is incorrect because sodium phosphate is a compound that has a single composition.
Sodium phosphate (Na3PO4) is a chemical compound composed of sodium ions and phosphate ions in a fixed ratio. Unlike a mixture, which can have varying compositions, a compound has a definite chemical formula and a consistent ratio of its constituent elements or ions.
