Here's how the name is derived:
* Sodium: This is the name of the cation (Na+).
* Tetrahydroxo: This indicates the presence of four hydroxide ions (OH-) coordinated to the central aluminum atom.
* Aluminate: This refers to the aluminum anion (AlO2-) formed when aluminum loses three electrons.
* (III): This Roman numeral indicates the oxidation state of aluminum, which is +3 in this compound.
Therefore, the complete name of the compound NaAlOH4 is Sodium tetrahydroxoaluminate(III).
