Let's break down the name of the compound given in the question [tex]\( FePO_4 \bullet 8 H_2O \)[/tex].
1. Identify the elements and their compounds:
- Fe: This is the chemical symbol for Iron.
- PO_4: This represents phosphate.
- 8 H_2O: This denotes that there are 8 water molecules attached to the compound, which is called octahydrate.
2. Construct the name of the compound:
- Part 1: The metal in the compound is Iron.
- Part 2: The non-metallic part is phosphate (PO_4).
- Part 3: The compound contains 8 water molecules, which is termed as octahydrate.
3. Combine the parts correctly:
- The full name of the compound becomes Iron phosphate octahydrate.
Given the options:
A. Fermium phosphate decahydrate
B. Iron phosphide dihydrate
C. Iron phosphate octahydrate
D. Fermium potassium octahydrate
The correct name, therefore, is:
C. Iron phosphate octahydrate
